GCBASIC Code

Updated GLCH.H to support HX8347G
New HX8347G library
Revised ILI9341 to support faster clear screen

Update to PCD8544 GLCD to support hardware SPI

ReadPixel_ILI9341 added to library

Fixes for compiler bugs:
- Fixed null pointer exception when the last script line processed is End If
- Fixed two bugs in new temporary variable overwriting protection code, one which could cause the same new temporary variable to be overwritten, and one which would lock up the compiler if there was a recursive call.

Added _v9081Patch=1 and _v9081Patch=2 for fix

Restore the cache value correctly in HPWMUpdate

Compiler additions:
- Fixed bug where temporary string variables were overwritten prematurely
- Added asm ShowDebug command - anything following this will have any constants replaced, and will then be inserted as a comment into the assembly at that location
- Replaced debugging nops in system.h with asm ShowDebug
- Temporary string variable sizes are now set based on the string to be copied into the variable - a temporary variable to store "Hello, world" would now be 13 bytes rather than 20 or 40 (depending on the chip).
- Command line /K:A switch now correctly passes all input lines to assembly file. Comment lines were omitted erroneously ever since this switch was implemented.
- Fixed bug in Rotate command which caused declarations for non-byte variables to be removed from the assembly when only the Rotate command operated on that variable

PWM16 for the Microchip 16bit PMW modules!

Tidy up by deleting all the demos - they are now secure in GitHub
