Added Support for custom video start time

1) The Start Time can be set via the data-setup array
2) If 'start-time' is not present defaut time of 0 seconds is used
3) To set a custom start time for a video simply set start-time to be
equal to the number of seconds from the start of the video you would
like to begin at.
For Example: "start-time":80 means that the video will start at
timecode 00:01:20 -> HH:MM:SS
Added Flag for loop support with custom start time

The flag is used to determine if loop video is set to true,
once the video starts, options_['loop'] will always be set to false.
This allows the onEnded event to always be fired and allows us to set
custom start-time for when the video loops.

(When loop is normally set the onEnd end onPlay events are never called
their for this flag is necessary)
Updated sandbox example to point to correct source list
Added mocha for Testling
Added details about including issues in pull requests.

Fixed Start Time Offset

Implementation has been modified to utilize the firstplay event to set
the custom start time offset of the video.

If in the data-setup array an attribute of "starttime" is specified,
then the video will start playback from the passed index in seconds.

Note: Video will only start from this index on first play only.
