Version 0.9.3

* close [issue #6](https://github.com/zaufi/kate-cpp-helper-plugin/issues/6): allow `RPATH`  for LLVM directory.
  Possible this is gentoo specific issue, so further investigation needed  for other distros... (feedback welcome).

* move proprocessor macros into a separate completion group.

* get rid of hardcoded completion item sanitizers -- now they can be configured via plugin  settings dialog.

* configuration pages refactored, the new one has been introduced: _Clang Completion Settings_.

* a bunch of other internal refactorings.
