* refactor out the common menu code from several base*.html classes into main-menu.html
and put the raw links into a unordered list (which makes it easier to create dynamic
menus as we cannot insert block items into inline items in strict mode)
* query the list of available projects on every request and set them for every template
in Middleware.php
* make the popup menu pretty
"usherConfigured" to denote whether we render links to the usher
control functions in the forge administration
* src/IDF/Scm/Monotone.php: moved IDF_Scm_Monotone_Stdio into
separate file src/IDF/Scm/Monotone/Stdio.php
* src/IDF/Scm/Usher.php: new class to query and modify the state
of a running usher instance
* src/IDF/Views/Admin.php: add actions to query the list of
configured servers, edit their status, view their open connections
and control the state of the usher as a whole
* src/IDF/conf/idf.php-dist: optional usher configuration added;
mail address of monotone-users added; spelling changes
* src/IDF/conf/urls.php: added needed URLs for usher actions
* src/IDF/templates/idf/gadmin/base.html: usher links
The first tab of the administration was not used, so I removed it to
remove the clutter, it will be reactivated when it will be possible to
perform forge configuration from there.
