[ITS] Added support for including several filters in type_analysis.
Added new filter for ITS: TicketType.
Improved filters query so now it supports the new type_analysis format:

['ticket_type,ticket_type,ticket_type,ticket_type,ticket_type',
 '"normal","enhancement","major","trivial","critical"',
 'OR,OR,OR,OR,OR']
Implemented global filter for ITS. Just pending final details.
Completed ITS global filtering.
Fixed use case where no global filtering exists.
Do not follow data and db dirs in git.
