- FA -> LRG: fix double addition of rules
 - Glushkov: use different state/nonterminal names. Names are generated via hexavigesimal with symbol id appended
 - Thompson: use different state names
 - Brzozowski: fix numbering - start at 0 so hexavigesimal starts properly at A
 - RRG -> FA: if createUnique is used, then use A' instead of A0

 - tests: correct exit values to determine if process reached timeout or segfault

 - Make interfaces interfaces - remove member variables from them
 - Remove redundant interfaces
 - Remove redundant classes aka StateNonTerminalMap. This functionality can be achieved by simpler std::map
 - Ensure second call of convert() will not fail by creating everything on fly. Thompson is the only algorithm where output must be member variable to make things simple. C11 will hopefully resolve this.
 - Hexavigesimal for Brzozowski classes.

 - Removal of libaregexptree/RegExpAlphabet
 - Method getting regexp alphabet moved to alib/RegExp, alib/RegExpElement
 - Method getting get symbols list in order moved to aconversion/GlushkovTraversal as Glushkov algorithm is the only one using it
 - Reflect changes throughout project

 - RE to FA: comments
 - RE to RRG: fix generating epsilon rules and workaround for issue #22

This reverts commit 832a57e7.

Conflicts:
	aconversions/src/re2fa/Brzozowski.cpp
	libaregexptree/src/RegExpOptimize.cpp

 - new dlls:
  - libaderivation - derivations of RE (+ integrals soon(c) )
  - libaregexptree - algorithms on regexp tree (optimizations, special traversal)
 - aderivation library moved outside conversion directory
 - Deleted regexputils. Methods moved directly into alib or libaregexptree
 - Reflect mentioned changes in conversion algorithms
 - Change to makefile (compile alib first, then libs, then binaries)
