Clean up clutstore.* and add LRU cache
This commit adds a true LRU cache to `rtengine` which is used in the new `CLUTStore` class. The code in `clutstore.*` was cleaned up with C++11 features and small optimizations taken from my `clutbench` project. The `CLUTStore` class was converted to a true singleton.
