fix misspellings & gcc v3.4.6 warnings
...
1. fix typos / misspellings
- Fix misspelling within comments, variable/function names, stdout messages
- changes the name of an error code: ```stlBoundries``` changed to ```stlBoundaries```. Alias old name (```stlBoundries```) to the new one.
2. fix gcc v3.4.6 32bit & 64bit warnings
- fixes gcc v3.4.6 warnings, except for those in tinyxml and "-Wmissing-declarations" makefile warnings
- in Preprocessor::handleIncludes(), replace a ```vector <bool>``` with ```stack<bool>``` (see ```vector<bool>``` warning below).
- this is the only ```vector<bool>``` in the codebase
- ```vector <bool>``` is actually a case of template specialization, and is not recommended, according to the following links:

http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2160.html

- in the codebase before and after this change, testrunner SEGVs in a number of places on gcc v3.4.6, including ```Check::~Check()```, among others

Small refactoring to compile more matches
...
*** Timing of the test suite ***
Four runs were used to calculate the average run time.
Before: ~1,103s
After: ~1,066s
Speed up: 3,35%
*** Timing of internal projects using STL ***
Before: ~8,301s
After: ~8,207s
Speed up: 1,13%
So the real world speed up is roughly 1%.

The profiler showed we were spending quite some time in
Tokenizer::simplifyCallingConvention(). The multi match
pattern in there is "complex", at least for the on-the-fly parser.

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).

Change location of %op% operator in multicompare

When the %op% operator is the first element
of a multicompare, it properly executes Token::isOp().
Otherwise it uses it's "internal implementation".
Workaround inspired by Edoardo Prezioso.

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'.

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.
