410e4502ee Added a 160x192x2 TGI (graphics) driver to the VIC-20 library. 
The driver requires a special linker configuration: "vic20-tgi.cfg".
The VIC-20 computer needs at least 8K of expansion RAM!

"tgidemo.c" needed to be adjusted because the VIC-20's vertical (y) range is greater than its horizontal (x) range -- the opposite of most other platforms.  Also, the circle demo would jam on the VIC-20.

d7afadb2fe Factored out target specific inclusion of target header. 
So far conio.h included the target header to get the CH_... and COLOR_... macros. However tgi.h never did the same to get the TGI_COLOR_... macros. And some time ago the JOY_..._MASK macros moved from joystick.h into the target header yet joystick.h didn't include the target header.

Why wasn't that issue detected so far? Because about every program using TGI and/or the joystick uses CONIO too and therefore includes the target header that way.

However, conceptually it's clean to factor out the target header inclusion and have tgi.h and joystick.h do it like conio.h.

Apart from that user code may make direct use of target.h too.

4aa00e84e1 Removed tgi_load() and all corresponding infrastructure. The idea behind tgi_load() was to be able to describe a TGI mode in a target-neutral way by resolution and colordepth. However it turned out that there arn't any cc65 targets sharing any resolution. As a result the only working target-independent approach for a TGI program is to call tgi_loaddriver(tgi_stddrv); and then look up the resolution provided - and to adapt to that resolution.
