Fix notice in admin area.
Set default mode to 'imap'.

This fixes some notices.  Might switch default mode to 'inbound' in the future
for shared hosts.
Be nice to those that are symlinking the directory.
Improved email signature removal.

Forgot to trim whitespace when checking for the last line created by
email clients. (See commit f492856.)

See #6.
bbPress: Add back support to reply to non-BuddyPress topics by email.

The latest release of bbPress (tested with v2.5.4) fixes some issues
relating to the post link, which was holding up enabling this feature.

See #24.
bbPress: Ensure RBE author stays subscribed to topic.

When a user replies to a non-BuddyPress topic, we need to explicitly
tell bbPress to keep the topic subscription for the user.  Otherwise, the
user will be unsubscribed after posting by email.

This commit sets the $_POST['bbp_topic_subscription'] flag so bbPress
see this.  This is due to how bbp_update_reply() works.

See #24.
bbPress: Comment out 'publish_replies' cap check.

This caused issues if the auto-role option is disabled from the bbPress
admin page.  I don't think we need to explicitly check for this cap anyway.

See #24.
Update readme.md.
Bump version to 1.0-RC3.

Making our way slowly-but-surely to 1.0 :)
