Timing of 'chosen:showing_dropdown' fixed

Currently the event is triggered before dropdown LI's
are created. This commit corrects it by moving the
trigger event at end of method. A JSFIDDLE was created
to demonstrate the issue.

By moving the event it enables developers to add
whatever additional code or styling to the dropdown
menu options such as images.
Fire the `chosen:showing_dropdown` event only after results
are totally built.

add support for cut/paste events

A short delay (currently 50ms) is required after the paste event for the
pasted text to enter the textbox.  Then we can trigger a `keyup` event as if
that copy had just been typed into the box manually.
