Changed some TABs to spaces in macros, that should end the conflicts because we use different tab sizes (4 vs 8)

Fixed some bugs to make GCC work. I needed to change SimpleValueAction to take the function as a variable as opposed to a template parameter - GCC won't accept pointers from a base class in templates.

Added some REFLECT_ macros, so the reflection code doesn't have to mess with the internals of reflection.

If this doesn't work in GCC, the COMMA definition could be made only for MSVC, then GCC sees DECLARE_TYPEOF(map<int COMMA string>). GCC doesn't need DECLARE_TYPEOF anyway.

Keyword expansion now works, still todo:
 - marking parameters, e.g. "Cycling 2W" -> "Cycling <param-mana>2W</param-mana>"
 - user interface for toggling reminder text
 - user interface for keywords

Removed DECLARE_TYPEOF2; replaced with double-parenthesized macro calls. (GCC doesn't accept the other way in all cases.. I don't know whether MSW accepts this way.) Fixed a few resource names.

Added 'snap to grid' to symbol editor

Added 'collapse' option for card notes;
Made variant of  DECLARE_TYPEOF for maps (two template arguments).

Added scriptable 'enabled' to symbols in symbol font, used instead of scripted filenames. This means changing the tap symbol style now works;
Added localisation for games, stylesheets and symbolfonts;
Warnings from Reader are now shown onIdle;

Reverted resource references for combine_something, you can't use tool_image here, because on MSW that only works for .bmps'
Added dependency stuff to invalidate Choice images;
Fixed 'duplicate' in symbol editor

Updated HoverButton, now an actual custom control, added focused and down states;
Added Help->Website

Fixed symbol change crash. The symbol change menu still hovers around being completely out of date from the actual symbol, and the changes don't nessecarilly take place on the card either. Perhaps a caching problem?
