fixed double loadbang regression due to implementation of internal pre-loadbang mechanism for the preset engine.

fixed segfault with netsend/receive using tcp packets where netreceive is deleted while netreceive is connected to it (after which sending data to netreceive would result in a segfault)

fixed regression where iemgui widgets within GOP sometimes got redrawn even though that was completely unnecessary

fixed gop getrect detection for objects that have been previously relocated to allow for consistent positioning

fixed resetting of cursor and proper highlighting logic. further refinements to the multiconnect cursor/key logic

Fixed bug http://sourceforge.net/tracker/index.php?func=detail&aid=2457992&group_id=55736&atid=478070; hopefully also fixed incorrectly reported hit/selection boxes for nested structs (like the one reported in the previous bug report)

fixed segfault when closing array window/subpatch due to lack of checking of valid resize/move hook pointers

added ability for preset_hub to write/read presets or entire scenes from files. Improved documentation to reflect new additions and to improve existing.

numerous bug-fixes for mouse down/up and key press combos (e.g. shift-clicks for multiconnect and dragging within an object)

improved nlet highlighting (integrated it into glist), fixed bug with multiselect with mixed objects (accelerated and legacy)

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.
