My first commit, yay! ;)

(Confidence score calculator integrated into the build system)
Removed most redundant operations from confidence score calculation;
confidences for the full DB now take 4-5 hours to build instead of 4 days.
BuildBundle: UniprotFullname map parser: namingConventionB changed to UniProtKB-AC
BuildBundle: ProteinTranslator: strongest convention changed to UniProtKB-AC, minor performance improvement added
download_sources.sh: maps using non UniProtKB-AC target removed
