qmljs: adding qrc support

Qmljs now keeps a cache of parsed qrc files, and can resolve "qrc:" links.

This breaks the assumption that the name that the qml files has on
the filesystem is the one that qml sees, and that contents of
directories can be found just looking at file whose path starts with the
directory path.

Currently the first file is used when multiple qrc files contain the same
path, but support for strict and weak path resolving is already there.

At the moment only qrc files for projects that call updateQmljsCodeModel
are updated.

ChangeLog: QmljsSupport: Imports using qrc links are resolved.
