Add-ons [AP] Daily Goal 2.5.0

• Allow admins to choose which nodes will count towards the post & thread goals (suggested by @Ozzy47)
• Allow admins to choose the color of the progress bars
• Allow admins to disable post, thread, or member registration goals
• Add widget and progress bars for the goals (suggested by @Andro)
• Add daily thread & member registration goals (suggested by @Andro)

This update no longer hooks into the posting process to add +1 to the goal counter, and instead adds a cron job that runs every 10 minutes to count how many posts have been made today based on their timestamps. Therefore, it should fix all known issues, and even include posts made before the addon was installed.

It also adds a permission for viewing the counter.
