Refactoring information messages.
...
Currently the information severity messages are outputted as error
messages with Severity::Information. This causes constant confusion
as people think it as mildest error severity (and rightfully so).
When it was meant to be for printing messages about the checking
procedure itself (like missing header files etc).
So I'm adding a new function for the ErrorLogger for printing these
informative messages. This makes clear the distinction of errors
found from the code and messages related to the checking itself.
It also makes it easier for clients to handle these separately.

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 class Token: changed handling of different types of tokens.
...
- Replace _isNumber, _isName, _isBoolean attributes by a single _type attribute (enum Token::Type), because not two of the old booleans could be true at the same time.
-> 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)

Changed relationship between templatesimplifier and tokenizer:
...
- Pass a tokenizer to templatesimplifier to reduce code duplication (Make use of Tokenizer::reportError; remove redundant TemplateSimplifier::addtoken2) and amount of arguments passed to functions
Removed ctor and dtor implementation from TemplateSimplifier: This class shouldn't be instanciated.

...
- Replaced Scope::access by a locally stored std::map, because its a temporary status variable that is only necessary when creating the symboldatabase
- Moved SymbolDatabase::argsMatch to Function::argsMatch, because its function specific
- Improved Scope::findClosingBracket: Improved reliability, made it static and faster

Refactorized stringification of tokens:
...
- Function that stringifies one token: Token::stringify()
- Functions that stringify a list of tokens: Token::stringifyList()
-- Single and powerful "base" function, used by several "light" functions
Refactorized
- testtokenize.cpp and testsimplifytokens.cpp: Use improved stringification functions instead of several local implementations
- Avoided redundand creation of std::string when using TestTokenizer::tokenizeAndStringify and in cmdlineparser.cpp
