Massive Keymap Reformat! + Layout/Splash updates

I have the name: LudvikKoutny
This user started a thread on: https://devtalk.blender.org/t/2-8-keymap-file-formatting-mess/5279 about how blender just chews up keymaps, dropping items etc.
And, oh boy, was that my experience!
The past handful of updates have all been to try and resolve issues with one or more commands not functioning in my template vs blender default and industry standard, but the rub has been that after each update (editing the keymap inside of blender) I export it from blender, which corrupts it, and then I end up with different issues the next time.

I discovered that blender had just deleted 30-40 items from the Sculpt, Font, Image Paint and a few more from 3D View, it had also added empty keymaps for Gizmo and Header, which weren't present when I compared against the built-in keymap.

Sooooooooooooooooooo, I manually reformatted and indexed the BLUi keymap. It is functional, but the focus was on trying to increase readability and editability for humans.
It will be a while before I trust blender to export a keymap properly again, so it made sense to create something that I could easily edit manually in a text editor.

Splash screen is now a little more generic, to permit version #, credits etc

Layout has changed slightly, I wasn't happy sculpting in the little viewport, so I renamed the existing workspace to 'Layout', and added a second workspace called 'Model / Sculpt' that doesn't have the File Browser, Outliner or Properties showing, and doesn't hide the Tool Settings by default.
