- Added SetCompressorDictSize (only works for LZMA) - Added SetCompressionLevel (only "works" for zlib and bzip2) - doesn't work for now - Section is only supposed to get 4 parameters if /o is specified - Updated version numbers git-svn-id: https://svn.code.sf.net/p/nsis/code/NSIS/trunk@3190 212acab6-be3b-0410-9dea-997c60f758d6
