Chrome 6+ fixes ontouchstart in win touch detection

Fixed preventDefault:true for flick. Fixes #2530951

Reset start time on first move, to fix use case where use mousedowns, touchstarts but doesn't move their finger for a while. Fixes #2530187 Still need to fix the case where user changes direction before mouseup/touchend. See #2530220.

Fixed y axis param handling in Flick gesture. Fixes #2529767

API doc tweak - closed A tag. No code change

Don't preventDefault on mousedown/touchstart by default. click gets swallowed on touch devices if we do this. Fixes #2529279. On touch devices, nothing else is required. On mouse devices, if you're setting up a touch listener, you need to account for differentiating between click and a drag (click gets fired for a drag)

API Doc tweak. No -min files were hurt in the making of this commit point

Added API docs for context, additional args. Fixes #2529150

Added support for preventDefault config parameter for gesturemove and flick subscribers. DD should now be able to pass through it's validHandle function to preventDefault, and drop it's independent time/distance threshold implementation and use gesturemovestart's. API docs has details. Fixes #2529131

1. Normalized e.preventDefault(), e.stopPropagation() etc. between touch and mouse. No need for e._orig anymore, so removed it. 2. Fixed button filtering to default to 1 (vender left) instead of 0 (W3C left) and added e.button for touch - which defaults to filter value if provided, else 1 (so app developers don't need to change their if clauses for mouse vs. touch if they're working with e.button) See #2529131

APIDoc tweaks. No -min files were harmed in the making of this commit point

Fixed handling of null in node.on('gesturemove', fn, null, context ...) signature

Added API Docs for Gestures. Changed flick e.velocity to incorporate direction (-ve, +ve) (and changed node-flick, scrollview listeners to match). Fixed method name refactor in paging plugin

Added check to prevent divide-by-zero to prevent NaN direction for 0 minDistance, 0 minVelocity

Fixed synth event integration issue. emitFacade false not needed for DOM event pass throughs anymore

Temp. hack to avoid touch interface on Chrome 5

Refactored flick based on synth event changes. No delegate support

Updated move impl to use fireFilter

Fixed flick fireFilter impl

filterSubs => fireFilter. New filtering approach. Replaced the Do.before() on ce._procSubs for all synths with A per-subscription Do.before() on sub._notify for only those synths defined with a fireFilter method. Rather than iterate over the subs (and deal with the fact that filterSubs was called twice per fire--once for on() subs, once for after() subs), fireFilter(sub, fireArgs, thisObj, ce) is a boolean function. Return falsey to skip that sub. The name may change, but not to "Bob".

Changed flick to pass through DOM event facade, instead of wrapping it

Integrate SyntheticEvent filterSubs support

Fixed flick plugin reverse scroll and direction

Node Flick plugin. Still early WIP. Committing for safekeeping

Added minDistance, minTime and button param support to movestart synth event

Clean up based on review feedback from lsmith

Fixed flick param parsing

Added some basic comments/api docs to flick

Cleanup and added root, standAlone support

Passing through DOM e object for move events. Looks like CE won't let me change target/currentTarget.

- Normalize target/currentTarget for gestures - Add event-gestures loader meta-data (also picked up jsonp meta)

Check for node === document, added button to e (temporary, until we have full synth event arg support)

Committing early event-gesture work, just so I don't lose it while the laptop is in the shop. Still needs refinement.
