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

*** Timing of the test suite ***
Four runs were used to calculate the average run time.
Before: ~1,103s

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%.

Improved STL checks:
...
- Added performance checking for .c_str() for return values and function parameters (#1079 )
- Added more containers (basic_string, C++11 containers) and more functions to checking (.at, .resize, .reserve, ...)
- Make use of symboldatabase in missingComparision check

Change every 'tokAt(1)->' to 'next()->' because 'tokAt(1) == 0' is equivalent to 'next() == 0', hence the equivalent cppcheck crash.

Fix namespaced types for auto_ptr new[] errors
...
This fixes false negatives for code such as:
std::auto_ptr<foo::bar> p(new foo::bar[10]);
The idea is to find a "new", search for the end token ";", then see if
the declaration ends in a closing square bracket. Also fixes other cases
that checked for "new %type% [" so that they work with namespaces.
