rockbox/apps/gui/skin_engine/skin_tokens.c
Jonathan Gordon 18a8e529b5 more wps->skin engine work.. 
start redoing memory management in the skins to use a single larger buffer instead of lots of arrays for things like images and progressbars.
This commit removes the limit on the amount of progressbars allowed on the screen, still 1 per viewport, but unlimited otherwise(!)
Also a larger buffer for remote targets, same size for non-remote targets but very easy to make it bigger (technically removed the 52(?) image limit in skins, except still limited to 1 char identifiers)
Unlimited "string" tokens now (limit was 1024 which was rediculously wasteful)
