Tools: shader/effect cache works incorrectly sometimes

[niello]

1. Revert engine and rattling-coast to the state before a703998
2. Add 'notex' (non-textured) versions of CEGUI shaders
3. Build only new shaders
4. D3D11 rendering is broken, VS - PS signatures mismatch.
5. Clearing shader DB, shaders and effects and rebuilding everything helps
