Gui select bcb6 projects (#1258)

* Allow selecting bcb6 projects in "Analyze" -> "Files..."
This change also splits the filters for files which can be analyzed into multiple entries and includes a helper class to construct filter strings.

* move FilterStringBuilder to its own class and document it

* add new files to .pro

* add missing include for Q_DECLARE_TR_FUNCTIONS macro

* re-run astyle

* allow to import bcb6 project when creating a new cppcheck project
exchange class FilterStringBuilder with a toFilterString() helper method

* add missing include
