Basic brush resizing tools POC

[Nocxr]

Hey! I just found out about Lorien recently and like it a lot so far! I wanted to be able to change the brush size on the fly without having to use the mouse so I made 2 simple ways to adjust it:

1: Set increment Up/Down Keys ( [=down, ]=up )

2: Holding an activator key to resize on the fly with the mouse/pointer ( F=resize )

I've added a extra tab in the settings menu to control the size step count for the incremental adjustment, as well as a multiplier (or sensitivity sort of) for the resizing:

I just wanted to throw this out there incase you had any interest in it, I'm sure there are better ways to do these but I wanted a base for myself at least. Please let me know if you have any suggestions or ideas and thanks again for the awesome program!

As user @therealrobster already suggested in #88 :

CTRL Mouse wheel should make cursor / brush larger / smaller.

This would feel most natural for most users.
