installer: Macro tweaks
Move all application metadata to appinfo.h; add version resource
Change project name, version and crashback URL; update About dialog

Hopefully the change in project name is temporary.

About dialog changes:

- Forego use of wxAboutDialogInfo in favor of finer-grained
  control of building the dialog directly
- Add links for the listed contributors and a few words
  describing their major contributions
- Remove "All Rights Reserved" line, as it makes no sense
  with the GPL license
- Make sure that non-ASCII characters display correctly
  regardless of compiler or system codepage
Remove crashback binaries
Add crashback.php, a reimplementation of crashback.pl
Add CrashBack to VS2010 solution
Fix 64-bit compilation
