Refactored project structure (also a step towards #6)
Simplified MutableDHash.ensureCapacity()
All subprojects except the lib moved on Java 8
Meta projects cleanup: made fields and classes final, optimized imports and other minor fixes
Implemented QHash/DHash switch as alternative to LHash. QHash by default.
Fixed FindBugs configuration (broken by 8f6b1c3) and some minor defects spotted by FindBugs
iterator() and cursor() methods should copy expected modCount before checking if the hash has no removed slots
Pull value copy in HashBulkMethodGenerator as well as key (affects map.hashCode() with long or double values). Some refactorings.
Container and HashContainer documentation fixes
Made HashContainer.currentLoad() to return double instead of float
Fixed bug in ScalerTest
Implemented Updatable mutability (with massive duplication in implementations so far)
