PKEuS e0a3ca0845 Refactorizations in class Token: changed handling of different types of tokens.
- Replace _isNumber, _isName, _isBoolean attributes by a single _type attribute (enum Token::Type), because not two of the old booleans could be true at the same time.
-> Add support for lots of different other kinds of tokens. (More precise checking of token type possible)

PKEuS 8cbed66089 Changed relationship between templatesimplifier and tokenizer:
- Pass a tokenizer to templatesimplifier to reduce code duplication (Make use of Tokenizer::reportError; remove redundant TemplateSimplifier::addtoken2) and amount of arguments passed to functions

Removed ctor and dtor implementation from TemplateSimplifier: This class shouldn't be instanciated.
