improved cursor motion for up/down/home/end; text editor now remembers cursor positions (instead of indices) when applying scripts.

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).
