Replaced static variable isCPP in Token (was not threadsafe):
...
- Encapsulate parameters passed through AST compiler functions in a struct
-> Reduces maintenance overhead when changing them
-> Contains parameter indicating if the file is C or C++
- Added eKeyword Token type (at the moment, only true for C++ keyword "delete", but should be set for other keywords as well)

> "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*).

This fixes false positives for the C++ template case since
the brackets in "template < something >" are not comparison operators.

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.

Updated VS9 solution
New VS10 solution that builds cppcheck into a dll used by cli and testrunner.
Functional changes and advantages of new solution:
- Share code between testrunner and cli; ability to share code with gui as well (not yet implemented)
- Files of /lib are no longer compiled twice (should improve build time on single core machines)
- Added configuration for building with PCRE support
- Executables are build into /bin (/bin/debug in debug mode) folder (Should no longer require rebuild when switching between debug and release)
