Add bearing filter support to viaroute, trip, nearest, and distance

Browse Source 
table plugins.
Make bearing range configurable by adding a comma-separated second part
to the bearing paramenter, like so:

    b=<bearing:0-359>(,<range:0-180>)

If no range is supplied, it defaults to +/- 10 degrees.
