Load data for all plugins on plugin management page.

include.php: file to include to make creation of entry points easy
index.php: move most of this file into include.php (and include it)
plugindata.php: a separate entry point using include.php; load ALL plugins found, and write data gathered to plugindata.out.php
.gitignore: add plugindata.out.php
actions/pluginsadminpanel.php:
        * use plugindata.out.php's common_plugindata() instead of StatusNet::getPlugins()
        * give a button linking to plugindata.php, to refresh plugin data
lib/pluginlist.php:
        * use plugindata.out.php's common_plugindata() instead of thowing the 'PluginVersion' event to currently enabled plugins
        * for the enable/disable forms: was: if (!$disabled) now: if ($enabled && (!$disabled))
lib/statusnet.php: move the list of filenames for a plugin into it's own public static function; this is used by plugindata.php
