Simplify some generalized math formulas:
...
Now the 'sin^2+cos^2=1' and the 'sinh^2-cosh^2=-1' code can handle, for example: sin^4+cos^4=1, sinh^10-cosh^10=-1.
Also, the arguments can be also multitokens, so that it's possible to simplify, for example: 'sin^2(k())+cos^2(k())=1'.

Fixed wrong tokenization of some math formulas:
...
The two formulas: sin^2+cos^2 = 1 and sinh^2-cosh^2 = -1 are true iff the two arguments are the same.

Use more Effective C++ code style in SymbolDatabase class:
...
1)The SymbolDatabase::findScope code is moved to the const-version. The non-const version is reimplemented as the combination with const_cast and static_cast.
2)Unrelated: change style of the declaration of some functions (the '*' is moved near the function name).

Use more Effective C++ code style in Token class:
...
1)The non-const version of Token::tokAt and Token::linkAt now will use a combination of const_cast and static_cast to remove duplicate code.
2)The non-const versions of Token::find(simple)match are added, in order to avoid the usage of const_cast outside the Token code.
3)As a consequence of 2), an useless const_cast applied to a call of Token::findsimplematch in Tokenizer code is removed.
