[skeleton] Add an entry point and configuration for running a Pyramid application
We add a `pyramid_main` function in __init__.py that instantiate the WSGI
application using "cubicweb.pyramid"; this is defined as an entry point (in
setup.py) so that pserve_ can find it.
Alongside comes a development.ini file which includes basic settings so that
running a Pyramid+CubicWeb application works (only the "instance=<appid>" may
be passed as a command-line argument). Logging is also configured there, but
only includes the cube at stake and cubicweb (others could be added if
needed).

Templates
---------
*Templates* are specific views that do not depend on a result set. The basic
class `Template` (`cubicweb.common.view`) is derived from the class `View`.
To build a HTML page, a *main template* is used. In general, the template of
identifier `main` is the one to use (it is not used in case an error is raised or for
the login form for example). This template uses other templates in addition
to the views which depends on the content to generate the HTML page to return.
A *template* is responsible for:
1. executing RQL query of data to render if necessary
2. identifying the view to use to render data if it is not specified
3. composing the HTML page to return
