MSON Utility functions

Added an MSONUtility file which contains the following functions:

* parseValue
* parseSymbol
* parseTypeName
* parseTypeAttributes
* parse TypeSpecification
* parse TypeDefinition

Also adds `StripMarkdownLink` function to StringUtility file.
missing `const` ? please try to focus on this – const reference should be your default habit (`const T&`) – anything else should be used only after explicit consideration...
