strands_webserver rewrite

[cburbridge]

We should rewrite the strands_webserver to remove the rather silly serving of .js files etc, and also to manage displays in a more sensible way. Further, in order to be able to use web.py for GUI, allowing easy server-side mongodb access .

The webserver should be replaced with a we.py server. Different paths should be used to explicity manage display numbers for multiple displays. Content should be provided to the webserver using a plugin system.

Agreed!

As no-one else has any jobs for me this week, I can make a start on it.

In #75 we have discussed that indeed we also need the ability to serve files that are in other (dynamically chosen) places. @cdondrup has the use case to stream media files via the webserver. This is similar to serving javascript and css files from another package (here: strands_webtool). So, we need to be able to serve files that are not all under one root dir. Different dirs should be served as different URLs, which clearly calls for a web.py solution. Indeed, the AAF control GUI server uses a similar apporach to serve its javascript files from strands_webtools that could be adopted.
