A few more fixes...mostly cleanups.

*Grouped some statements that it didn't make sense to put after a certain block of code (giving the impression that it had to be after this block).
*There is no need to set the value of the QSpinBox equal to that of the slider, when loading settings... their valueChanges() signals are connected to the opposite one's slot.
*Made a now unused variable be used, it was inconsistent in this code block, two times '1' was used, but other times a var set to '1' would be used.
*Moved some blocks of code from the loadSettings() method, into the constructor, since the loadSettings() method is called more than once, so it's more resource-friendly to do it this way.
