Use PNG icon and update to modern GpgEX icon
* src/bitmaps.cc, src/bitmaps.h: Removed. * src/gpgex.cc (getBitmap, getBitmapCached, setupContextMenuIcon): New. (gpgex_t::QueryContextMenu): Use new helpers. * src/Makefile.am: Update accordingly. * src/gpgex.h: Rmeove bitmap code. * src/icon*.bmp: Removed. * src/standalone.svg, src/gpgex_logo.svg: New. * src/versioninfo.rc.in: Update accordingly.
This fixes white background uglyness and should be more flexible
in the future to just update an image by using a PNG.
