Merge: nitweb: use ui-router

A lot of refactoring to replace ng-router by ui-router.

The finality is to provide direct links within documentations tabs:
 * link to dependencies: http://nitweb.moz-code.org/doc/core/graph
 * link to code: http://nitweb.moz-code.org/doc/core::kernel/code
 * link to linearization: http://nitweb.moz-code.org/doc/core::Array/lin

Also removed the special pages for mclassdefs and mpropdefs. They now link directly to their relative mclass/mproperty linearization:
* http://nitweb.moz-code.org/doc/core::Array/lin#pthreads::redef_collections$core::Array
* http://nitweb.moz-code.org/doc/core::SimpleCollection::add_all/lin#core$CircularArray$SimpleCollection::add_all

Demo: http://nitweb.moz-code.org/
