Enkel testing av main_window

See merge request !14

eneste betydelige endringen som ble gjort var å endre måten testen når tak i tab på fra å hente lagret widget inni tabben til å bruke 'currentWidget'. MainWindow lagrer nå 'self.tabs' istedenfor 'self.tab' (som skalerer bedre når det blir flere tabs)

main_window.py-klasser er flyttet til egne moduler

gir bedre lesbarhet

- fjernet overflødig bruk av max()
- beskrivelse til variabel i docstring

Dette kan testes med følgende script i roten av repo:

```python
from PySide2.QtWidgets import QApplication
from soitool.main_window import MainWindow
from soitool import main_window

app = QApplication()
main_window.app = app
window = MainWindow()
window.show()
window.tabs.currentWidget().view.produce_pdf('test2.pdf')
app.exec_()
```

#32 shortcuts fungerer nå ved flere TableModules i samme scene

previously the best practice for python was to put a linebreak after a binary operator, but going forward pep8 wants a linebreak before a binary operator. It's explained in the link above. There are errors for both of these cases, and previously they were both enabled... I disable this one because it's going against pep8

so to be clear: in our code going forward linebreaks need to be placed BEFORE binary operators

Å legge til noen rader, for så å fjerne noen rader fungerer ikke, men dette er trolig ikke et problem med keyPressEvent

Under følger en snippet som viser hva som ikke fungerte før:
```python
from PySide2.QtWidgets import QVBoxLayout, QApplication, QWidget, QGraphicsScene, QGraphicsView, QTableWidget, QShortcut, QHBoxLayout
from PySide2.QtGui import QKeySequence
from PySide2.QtCore import Qt

class QTableWidthWithShortcuts(QTableWidget):
    def __init__(self, *args, **kwargs):
        super(QTableWidthWithShortcuts, self).__init__(*args, **kwargs)
        shortcut = QShortcut(QKeySequence("Shift++"), self, context=Qt.WidgetWithChildrenShortcut)
        shortcut.activated.connect(self.say_hello)

    def say_hello(self):
        print("Hello")

app = QApplication()

# inside QGrahpicsScene
# shortcuts don't work..
scene = QGraphicsScene()
view = QGraphicsView(scene)
t1 = QTableWidthWithShortcuts(2,2)
t1.move(0,0)
scene.addWidget(t1)
t2 = QTableWidthWithShortcuts(2,2)
t2.move(300,0)
scene.addWidget(t2)
view.show()

# inside QHBoxLayout
# shortcuts work!!
layout = QHBoxLayout()
t1 = QTableWidthWithShortcuts(2,2)
layout.addWidget(t1)
t2 = QTableWidthWithShortcuts(2,2)
layout.addWidget(t2)
wrapper_widget = QWidget()
wrapper_widget.setLayout(layout)
wrapper_widget.show()

app.exec_()
```

Her er en snippet som viser hvordan denne løsningen unngår problemet over:
```python
from PySide2.QtWidgets import QVBoxLayout, QApplication, QWidget, QGraphicsScene, QGraphicsView, QTableWidget, QShortcut, QHBoxLayout
from PySide2.QtGui import QKeySequence
from PySide2.QtCore import Qt

class QTableWidthWithShortcuts(QTableWidget):
    def __init__(self, uid, *args, **kwargs):
        super(QTableWidthWithShortcuts, self).__init__(*args, **kwargs)
        self.uid = uid

    def keyPressEvent(self, event):
        if event.key() == Qt.Key_Question:
            print("{}: Shift and plus!".format(self.uid))
        elif event.modifiers() == Qt.ShiftModifier and event.key() == Qt.Key_Underscore:
            print("{}: Shift and minus!".format(self.uid))
        elif event.modifiers() == Qt.ControlModifier and event.key() == Qt.Key_Plus:
            print("{}: Ctrl and plus!".format(self.uid))
        elif event.modifiers() == Qt.ControlModifier and event.key() == Qt.Key_Underscore:
            print("{}: Ctrl and minus!".format(self.uid))
        else:
            super(QTableWidthWithShortcuts, self).keyPressEvent(event)

app = QApplication()

scene = QGraphicsScene()
view = QGraphicsView(scene)
t1 = QTableWidthWithShortcuts("A", 2,2)
t1.move(0,0)
scene.addWidget(t1)
t2 = QTableWidthWithShortcuts("B", 2,2)
t2.move(300,0)
scene.addWidget(t2)
view.show()

app.exec_()
```
