French translation

I have reviewed the french translation and tried to uniformize the vocabulary a bit. For exemple: phone call permission is always called "Appel direct" even where the english differs e.g. in access_notification_text.xml

If there is a good reason to do otherwise, let me know and I'll change it.

I haven't used the `&#223;` method of inputting accents because I have a proper french keyboard and utf-8 can handle them. Again if that's a prob, let me know.

I have noticed other things I might be able to help/enlighten you on.

1. ```<string name="title_activity_main">Gestionnaire PDroid</string>
<!-- title in the action bar of the app list screen: not visible? -->```
AndroidManifest.xml assigns a title to each activity, except that the main activity of an app gets the app name by default. You'd have to edit that. It is the `android:label=` property that counts.

2. ```<string name="applist_filter_settinggroup_label">Includes settings:</string>
<!-- label for the 'setting group' filter spinner. I can't think of better text for this, even though what I have put in is bad -->```
How about : Permissions requested

3. ```<string name="storage_error_body">The external storage cannot be accessed. If you device uses an external SD Card or Micro SD Card please ensure it is inserted and properly formatted.</string>```
Missing an r on youR.
