Dashboard regex tokens not matched

When using the following taff:uri, the dashboard did not correctly replace the tokens in the sample resource URI:

    taffy_uri="/member/{id:\d+}"

I adjusted the supplant prototype function to match all characters within the `{}`. I had to play some tricks with it to ensure that it could catch matches within `/`s and at the end of a string.

    { //Start with a curly brace for the match
    (.*?) //Match as few characters untili the next match
    ( //Start a new grouping
		}(?=\/) //Catch a curly brace immediately followed by a /
		| // OR
		}$ //A curly brace at the end of the string
	) //End the group

Will now match all items in the following resource uri:

    /member/{id}/county/{type}/{foo:\d+}/{foo:\d{2}}
