ecere/gui/EditBox; utf8: Updated EditBox UTF8 iteration; Fixed UTF8GetChar to return 0 in numBytes on null character
compiler/bootstrap; ide: Tweaks for using TDM-GCC multilib toolchain
- Not assuming 64 bit on _W64 (_W64 is defined with -m32 with TDM)
- Not auto-adding GCC prefixes
ecere/gui/EditBox: Fixed hanging caused by 308c3f8a022f58c179f5d52f87be2609fba4ddd8
- The EditBox assumed the UTF8_GET_CHAR macro would return numBytes = 1 for \0
  (But e.g. the text rendering in LFBDisplayDriver.ec assumed numBytes would be 0)
