Removed code duplication between testsuite and commandline tools. Also restructured source code of the tools.

Enabled all available mail storage types (those compiled in Dovecot) for the commandline tools and the testsuite.

Merged mail-raw implementations of sieve commandline tools and the testsuite, thus removing duplicate code.

Envelope: <> return path now always matches as the empty string, regardless of the specified address part.

Imapflags: resolved problem of hasflags encountering duplicate flags in flag lists contained in a variable.

Significantly improved handling of old/corrupt binaries and revised matching implementation in the process.

Fixed code emission for extension-defined variables and removed hardcoded paths from include extension.

RECOVERED FROM INCONSISTENCY: developed testsuite and binary dumping and fixed various small issues.

Almost finished implementing the store action. But, I still get strange errors when the mail transaction commits. Mail is stored though.
