GSOC work, code fixes + cache implementation

WARNING: cache implementation gives a link error to it's methods.
Created the cache called CodeCompleteDataCache in file include/basic/codecompletecache.hxx
This class should replace the std::vector< CodeCompleteData > int file baside2b.cxx
When issuing command "make basic", it compiles fine, but, when "make basctl", it gives a link error (ld returned status 1) to CodeCompleteDataCache's methods.
