Port of "translation overview" and "firebug lite" to Drupal 7

I've contributed a port of two Drupal modules to Drupal 7: Translation Overview and Firebug lite.

Translation Overview is a module, which allows admins to easily see which nodes in Drupal were translated to target lanugage. It also allows setting translation priority for each node.

Firebug Lite adds Firebug tool to Drupal without the need of installing Firebug in your browser.

My changes in Translation Overview were commited to repository and are included in latest beta of this module. Firebug Lite was posted in module's issue queue and not yet reviewed, but I hope it will happen soon.
