Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Improved error recovery in the Parser. The Parser skips to the next valid token if an illegal Declaration, Statement or AsmInstruction was found. Refactored a few things in Lexer.d and LexerFuncs.d.
