+ add RTTI unit from Joost's Attribute branch

* adjust unit to work without attributes
* adjust unit to work without unit list (TRttiContext.GetTypes is disabled due to this)
+ add ShortString support (due to an intermediary test I had done in $H-)
+ add unit test from Joost's Attribute branch
* adjust unit test accordingly (no attributes, no TRttiContext.GetTypes)
+ add ShortString tests
+ add testrunner for RTL-ObjPas tests using the new simpletestrunner
