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 bug id = 195
