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

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%.

Refactor the same expression check
...
Work out if a function is inconclusive when creating the entry in the
Expressions class instead of when checking the counts at the end. Store
the result in a new bool flag in the ExpressionTokens helper struct.
The pointer to symbol database and ref to list of const functions are
temporarily stored in the Expressions helper class to avoid passing
them in too on every endExpr(tok) call.
Use a const reference to ExpressionTokens in the check loop to avoid
repeating the it->second several times, which clarifies what that code
does.
