Removed old/duplicate editor images
Moved gold initialisation to earlier point, fixing bugs #20853 and #20734
Updated path for transparent version of default buttons
Fix "Shuffle sides" incorrect behaviour.
Clean up a variable declaration.

Making this a const variable gets rid of a compiler warning, and
making it a reference eliminates an unnecessary copy.
Move Miscellaneous to end of changelog.
Decreases the pango cairo dependency.

The dependency's version is decreased to version 1.21.3. This is the
version currently used in XCode (on the Mac). Upgrading there is
troublesome.

This partly reverts 2b939cebc7a4eea6ec6adae40c8396f836122940.
Make the x1,y1,x2,y2 variables within Lua match those in WML events.
