Add more code smells to titanium

Titanium is not updated for years and it completely misses code smells related to functionality developed since it was last touched (for example OOP). It would be good to add new code smells.

• Class is too large: it has too many local members/methods or it has too long functions
• Reserved words used as identifiers (eg. class)
• Too short variable names (except loop variables)
• Type embedded in variable name (eg. MyCharstring)
