Add detector class, test skeleton.
Detector with test

Layer dependency injection not yet implemented(can't work normally with file contents in detector).
Merge branch 'feature/wt9autodetector' into develop

Introduced facet detector, but without layer dependency injection -
don't know how to implement this at current time, because of some problems
with IDEA API(ru.crazyproger.plugins.webtoper.config.WebtopFrameworkDetector#createConfigurations -
main problems are here, no project -> no PSI).

#WT-9 fixed work 8h
fix 'unresolved reference' test
fix 'RenameFromXml' test case
