Performance improvement of IfcParse tokenizer (#82)

Browse Source 
* Applied MSVC tabify to IfcParse.cpp/h.

* Now Argument base class has throwing implementation for each conversion operator (removed those from derived classes).

* Added NullArgument class for the case when null arguments appear after setting elements.

* Now operator tokens are handled just like any other token.

* Refactoring: Token is now a struct with good fields, not a nameless pair.

* Now end position of token is set at its construction.

* Now type of token is determined on construction, as* function simply check stored type.

* Now int-s, float-s and some etc are parsed when token is created.

* Implemented simple way to remove spaces in parsing.

* Tokens are now created without allocations.

* Call RemoveTokenSeparators once for every token.

* Added temporary std::string object in lexer (for optimization purposes).

* Reimplemented asString without allocations.

* Parsing keywords without allocations.

* Added checks for type to tokenFunc::as*** functions.
