- common code of ChoiceValueViewer and MultipleChoiceValueViewer put into functions
 - RotatedDC can now draw text with shadow.
 - DECLARE_STYLE_TYPE macro and friends do slightly more.

Optimization: removed the conversion via wxImage for downsample_to_alpha (profiling indicated it was a bottleneck)

 - Optimization: common parameters to built in functions are no longer looked up as a string at each call, instead their integer ids are global constants
 - Optimization: some other minor tweaks.
 - Nicer --help message

Major changes:
  - when rotating, the top left corner of the rectangle stays in place.
  - ValueViewers get a dc that is pre-rotated/translated for them, i.e. (0,0) is the top-left of the viewer (with ValueViewer::getRotation).
  - moved 'angle' from individual Styles to the Style base class.
  - any rotation angle is now possible. angle is still an int for now.

This warrants a version bump

  "depends on: package version"

Added a 'tree list' control, which will be used for the package/updates window to be able to group packages

made update_checker compile in vc

Added infinity mana symbol.
Added insert symbol menus to all symbol fonts that were lacking them.
Updated font color choice for fpm promo to improve readability.

Corrected a mistake in extended image styling for magic-new and magic-planeshifted.

Adjusted fields for magic-planeshifts and alignment in magic-new-promo.
Added transparent mana symbol watermarks.

NOTE: I removed the default list of creature types. I don't want it 
gone, I just found the update easier to make without a simple list. If 
someone else feels like making one themself, I don't object.

Updates now work, and have been tested.
Made a few other updates.
To work on: aesthetics?

templates.
Still looking to find one source of a reference to 
"futsymbol_artifact.png" (case-sensitive)

Made it so that update window and set window can't be open simultaneously (don't explode the set by deleting the style, say).
Made update window enforce dependencies
Added update button to welcome window (need icon still)

Fixed all the dependency warnings for the magic templates

 Any use of a file from another package without a declared dependency will give a warning;

Also added some more _LOCALE_123_ macros so we need less format_string calls

entire perl script, which was somehow deleted).

Added/fixed versioning in data.
Added more framework to update checker.
