Implemented support for building cppcheck lib into a dll
...
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)
- Completely x64 compatible (contains also x64-debug configuration now)

Refactorizations in test suite:
...
- Implement createOnly mode in givenACodeSampleToTokenize so that only createTokens is called instead of tokenize
-> Ensures that no simplifications are done which could make the testing basic functions (like Token::Match) less accurate. We often don't need this simplifications in testtoken.cpp.
-> Ensures that no validation of the source is done (Fix #2104 )
- reduced overhead of givenACodeSampleToTokenize: Don't store a std::istringstream instance, avoid creation of std::string when ctor is called

-> Add support for lots of different other kinds of tokens. (More precise checking of token type possible)
-> Replaced instant checking of type for Operators, etc. by a value calculated at creation time. (Faster checking)
