Add magnetometer sensor implementation for iPhone runtime
There was some problems with the previous commit. Adding again ActivityIndicatorWidget, ProgressBarWidget and SliderWidget.
- Added library stlport.
- Still not finished, needs improvement.
- corrected path in _maapip.h (_STLP_NATIVE_CPP_RUNTIME_HEADER)
- removed warrnig : "../newlib/new"  file doesn't exist. Changed the
workfile.rb file, so that it will copy the new.h file from MAStd, into the
MoSync/include/newlib folder and it will name it "new" (not new.h).
Did that in order to make the include,
from the stlport/new file valid.
- test project for STL port
- added new test functions for std::set, std::stack, std::multiset
- added examples for predicates, functors
- added test functions for bitset, queue, priority_queue, stack, set
- added function for testing STL functors
Add video wigdet for iPhone runtime; Some small modifications in SliderWidget, ActivityIndicatorWidget and MoSyncSensor classes
- added tests for algorithms
- added some  more algorithms tests
- added test function for std::string
- added test function for functor adaptors
- added function for explaining iterators
Add some frameworks to the project's template.
