First skeleton of web server using bottle.
Correct a bug in the request handler that prevented from using more than one argument in a call request.

Rewrite the http server primitive which can now handle the following request:
- GET /motor/list.json
- GET /primitive/list.json
- GET /motor/<name>/register.json (eq. GET /<name>/register.json)
- GET /motor/<name>/<register> (eq. GET /<name>/<register>)
- GET /motor/<name>/<register> (eq. GET /<name>/<register>)
- GET /primitive/<prim_name>/call/<meth_name> (eq. GET /<prim_name>/call/<meth_name>)
- GET /request.json
Update the doc regarding the server (both zmq and http).
Centralize the version so when changing version you only have to edit the _version.py file.
It also provides a pypot.__version__.
