streamlined selection logic and added ability for pd to recognize system-wide @pd_extra variable within the path

finished importing the remainder of new K12 module abstractions, updated GUI to reflect them, improved key press capture, reformatted GUI object menu inside K12 mode to allow for more space

reenabled checking of scrollbars after startmotion->click (will need to check for possible regressions)

fixed regression in select due to 37c0cf15 commit which made it behave inconsistently thus making it impossible for floats to be treated as symbols (in cases where first argument was a symbol). Also introduced similar fix to the route object, thus allowing for second inlet to receive either float or symbol

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.
