Fix compiler warnings and comment/string typos

- fix g++ warning:
> lib/checkother.cpp:3779: warning: comparison between signed and unsigned integer expressions
- fix suncc warning (see [everything2](http://everything2.com/title/C%252B%252B%253A+static+extern+%2522C%2522 )):
> "lib/checkmemoryleak.cpp", line 578: Warning (Anachronism): Formal argument __compar of type extern "C" int(*)(const void*,const void*) in call to bsearch(const void*, const void*, unsigned long, unsigned long, extern "C" int(*)(const void*,const void*)) is being passed int(*)(const void*,const void*).
- prefer empty() / isEmpty() over "size() > 0" (cases not caught by stlSize)
- fix word misspellings (mostly comments, a few output lines)
- Parenthesis => Parentheses (both variations were used in the codebase)
- fix typo and wording ("never alwayw") in gui/test/data/benchmark/simple.cpp's CheckOther::unsignedPositive():
```
- "An unsigned variable will never alwayw be positive so it is either pointless or "
+ "An unsigned variable can't be negative so it is either pointless or "

Properly implement %op% for Token::multiCompare
...
Use tok->isOp() instead of doing it "manually".
This fixes false positives for the C++ template case since
the brackets in "template < something >" are not comparison operators.
Profiling showed using tok->isOp() is actually faster than before (-O2).

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'.
