command plugins are not to be prefixed with `Command`. This is because plugins
are not referred by their canonical names.

mainargs() function added to take out main-script parameters from command
line. Remaining parameters will be passed on to the sub-commands.
- Added a query_pluginr() method similar to query_plugins() method, except that
  it accepts an additional `pattern` argument that will be matched with plugin's
  canonical-names. Only matching plugins will be instantiated and returned as
  a list. query_pluginr() method is aliased as qpr()

- Sphinx documentation style. `min-width` of <body> tag is adjusted to 970px.

- Removed `IHTTPRenderer` interface from `pluggdapps.web.interfaces` module,
  instead a similar interface `ITemplate` is added to `pluggdapps.interfaces`
  module. `IHTTPResponse` plugins are expected to use this new interface.

- `webapp` command/scaffold is renamed to `newwebapp`
