Moved viewmodel position handling from CalcView to CalcViewModelView
Small fixes and changes

* Moved the menu bar stuff to one file for several reasons
* Fix for https://github.com/Facepunch/garrysmod-issues/issues/887
* Made so that editing presets doesn't remove default presets set by the
CPanel
* Aligned tabulation with Notepad++, since it's the most used for GLua
Removed one more file from send.txt
