KonsolScript and Game Engine Code

*implemented drawing of area selection for attempt to multiple selection
* implemented incrementing multiple selected shapes via SHIFT keypress
* implemented copy/pasting/deleting of multiple selected shapes
* implemented updating colors/location of multiple selected shapes
* implemented deselecting of selected shapes on ESC keypress
* fixed handling of attempting to multiselect versus resizing/moving shape
* minor code cleanup

* fixed shape-repositioning via Arrow Keys
* used GDK defines for KEY_xxx
* used Menu-item Shortcut-key to trigger Shapes z-order rendering
* moved z-ordering to Object-Menu
* pseudo-implemented File->New
* implemented multiple selection; still to update z-ordering/copy-pasting/deletion of multiple-selected shapes
* implemented scaling/moving/rendering-selection-box of multiple selected shapes
* some code cleanup

* implemented loading of Kage Studio File via BasicXml (see ./util/xml/)
* implemented Export PNG with non-transparent background
* minor fix on ffmpeg not being called on Windows even if on PATH environment_variable; requires ffmpeg located along with Kage Studio
* fixed error on exporting video with lower frame count than FPS settings
* fixed errors in saving Kage Studio File
* fixed error on calling non-existing external command on GNU/Linux
* renamed Makefile to Makefile.win
* some code-cleanup

BasicXML is a simple XML parser for-use of Kage Studio on loading KSF files; check testXmlBasic.cpp for demo

* implemented PNG export
* implemented PNG sequence export
* implemented AVI export
* some minor code-cleanup
* centered canvas on exported HTML5
* made non-canvas background darker on exported HTML5

* fixed Exporting HTML5 related to "closePath"
* fixed missing "Close Path" when Saving
* fixed rendering of zero-thickness
* resumed zero-thickness optimization

* fixed bug on moving shape/node via arrow-keys
* fixed Poly-made shapes
* fixed closed-shape creation; still to fix of handling non-closed-shape

temporarily removed dependency on register.h -- will place it back once User database is created for Kage Studio User Support Group :)

* implemented Node X/Y in Properties pane
* improved Kage Studio file format; making it more XML-compatible
* fixed incomplete vector data in exporting/saving
* depending on selected tool, Properties pane will display corresponding 'properties'
* minor optimization on handleNodesMouseUp

* implemented Z-ordering
* fixed node-deleting
* copy-pasting Shapes should now be inter-frame; previously it was only within the frame
