ui: Added custom tooltipping to code and graph (issue #195)

* Tooltips show node type with access specifier, reference count and fully qualified name
* Fields and global variables include the type name
* Methods and functinos show whole signature. Gets broken into multiple lines if too long.

Included changes:

* Upgraded to C++14
* fixed clang warnings
* Pass location of .srctrlprj file to build.sh script to load on launch
* Split off QtCodeField for showing highlighted and annotated code fom QtCodeArea
* removed TokenComponentSignature
* added TaskDecoratorDelay
