Floppy bitstream view, also major refactor of UI code

Browse Source 
Split the UI into separate bits.
+ Bits that are X11/GLX only
+ Bits that are 'pure' opengl
+ Bits that are UI related but not renderer related

Hopefully with help porting to other platformsI

# MII Version Changelog
## 1.7
* New animated about box, because, everyone loves a good about box.
* Added support for Write Protect of floppy disks; disk can be write protected manually, or if the file lacks write permissions, OR if the file format (NIB, DSK) doesn't support writes.
* New fancypants 'bit view' of the floppy are they are read/written, with a
heat map to show where the head was last. Drive 1 appears left of the screen,
drive 2 on the right. It fades out after the drive motor stops.
![Heat map disk viewq](docs/heat_map.png)
*DOS 3.3 Disk 'bitstream view' on the left, the green trace shows what's just be read.*
## 1.6
* Another big update, yanked the old DiskII driver, and replaced it with a
homebrew one, low level, with native support for WOZ (1 & 2) files (*read AND write!*) as well as NIB and DSK (read only).
