[server] Make connection pooler configurable and set better default values
Drop the configuration connections-pool-size and add new configurations options:
* connections-pool-min-size. Set to 0 by default so we open connections only
when needed. This avoid opening min-size*processes connections at startup,
which is, it think, a good default.
* connections-pool-max-size. Set to 0 (unlimited) by default, so we move the
bottleneck to postgresql.
* connections-idle-timeout. Set to 10 minutes. I don't have arguments about
this except that this is the default in pgbouncer.

Extending / overriding existing styles
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We cannot modify the order in which the application is reading the CSS. In
the case we want to create new CSS style, the best is to define it a in a new
CSS located under ``myapp/data/`` and use those new styles while writing
customized views and templates.
If you want to modify an existing CSS styling property, you will have to use
``!important`` declaration to override the existing property. The application
apply a higher priority on the default CSS and you can not change that.
Customized CSS will not be read first.
