added automatic resize of arrays when adding/removing points via ctrl+click, fixed a bug where array is not properly redrawn after a new point is created

Added support for multiline comments (with some help from Taylor O'Connor and Jean-Philippe Ouellet).

1. shift-click manual multi-connect
2. two selected objects multiple outlets to multiple inlets
3. two or more selected objects connecting to one unselected one
4. one unselected connecting to multiple selected ones
5. multiple selected ones connecting to one's multiple inlets OR the other way around (determined on whichever mode gives more valid connections)

Option 1 requires use of shift. Other options are based on what is selected at the time of making the first connection (others are automatically created based on conditions). Later consider adding special undo that undos all connections in one step, rather than multiple steps.

added ability for gop to intelligently detect when iemgui objects fit (or don't) inside gop window. the same also applies to dynamic changes to iemgui properties (size, font, label, delta, position, etc.)

made sure that properties windows associated with a patcher that is being closed are also closed at that time.

reworked getscroll once again (binding of the <config> was colliding with the scheduled calls from c and pd.tk)

another reworking of the pd.tk scrolling algorithm--it appears tcl/tk's update call at the end of the getscroll resolves any asynchronous problems encountered before...
