SimPHY (Beta Version) updated to 0.9

SimPhy is updated to new version which involves many tweaks and some long desired features. This updated is mainly intended for better visualization support to understand physics better.

What is new ?

Enhanced Free Body Diagram Support
Visualization of forces is even more better with this update. Now forces are rendered as solid arrows and can be customized with information or name of force displayed in diagram.
Custom Coordinate Axis
Simphy is more restricted to default Coordinate axes.now axis can be customized for direction of origin by simple drag and draw. In-formations for forces velocities and position of objects now shown or edited in new frame. I helps user in resolving forces or velocities in desired direction.
Organised Preferences Dialog
Preferences Dialog in Simphy is now more organised and includes support for free body diagram and vector information settings also. Similar settings are now grouped in same tab to make preferences dialog more intuitive.
More Powerful Tracer
tracer attached to a body can now display angular velocity along with linear velocity. It also supports customized display of velocity and angle info.
Tweaked Gui
Gui Elements for scripting are now more beautiful and consistant with design pattern. All gui elements now support transparency and resizing(except button and check box) as well.

Bug fixes and tweaks

Bug Fixes

Wrongly plotted acceleration in graph widget
Timer Widget did not start automatically
Frame rate preferences Settings was not applied properly
Reset simulation did not work for pre-loaded simulations
Some key events were not detected at all if canvas lost focus

Performance Tweaks

Tracer has now show velocity option
Components of forces can also be displayed.
Circle detection is improved a bit in mouse gesture.
Contact forces for a surface can be merged into single force, to make free body diagram less clupdy
