Bugfixes

• various bugfixes and improvements to VpDomain (see #239)
• various bugfixes and improvements to TreeAutomizer
• fixed a bug in non-relational domains concerning COMPNEQ by rewriting expressions. When in an expression expr = expr1 != expr2 the COMPNEQ operator is encountered, the expression is rewritten to expr = expr1 == !expr2 in all abstract domains (if dealing with boolean results).
• re-fixed another bug in non-relational domains evaluators.

Plumbing

• improved performance of Hopcroft tree minimization by working only on partitions instead of also holding a relation
• updated SMTInterpol to 2.1-404-g5f835ca

Known Issues

• README and Website usage instructions outdated (see #135)
• Startup with generated binary ./Ultimate stalls if no X display is available
