Support text() condition

- Added Antlr parsing of text() condition (as an optional additional to any query)
- Implemented text-condition combined with descendants
- Refactor descendants queries into using one more flexible Custom (native) Query builder
- Refactor ALL cpsPath queries to now use FragmentRepositoryCpsPathQuery (custom query builder)
- Refactor Antrl code to simply parsing of cpsPath and allow all combinations (no more query types, addresses CPS-436)
- Minor clean up of some minor convention issues in CpsAdminServiceImplSpec.groovy (found during groovy demo)
- Update .rst documentation of xPaths
- Fixed incorrect matching of additional list indexes using more precise SIMILAR-TO regex in postgreSQL
- Documented special chararter limitation (CPS-500)
- Checked for consistent use of term 'CPS path' in documentation and error message
- Included (updated) copyright in all .SQL test files
