[Release][v1.4.4] Multi-communities

This update adds the much request feature, multi-communities. Multi-communities allow you to group multiple communities into one and view it as a single feed.

You can find the option to add a multi-community on the Home screen's overflow menu (tap the 3 dots at the bottom right).

Change log:

• Added support for multi-communities
• Added setting to disable auto-linking phone numbers
• Changed the behavior of tapping an image in the card and large list layout. Tapping an image of a link post will no longer expand the image, instead it will open the link.
• Changed the UI for card/large list layout. Indicate when an image will open in the browser.
• Handle more network/server errors.
• Fixed a UI bug with the comment editor when the keyboard is expanded.

Known bugs:

• If you have a multi-community created from one instance and switch to another instance, if the multi-community includes a community that is not available in the current instance, a "page not found" error is shown even if it's just one community that cannot be found. The ideal solution is (1) show a message indicating which communities are not found on that instance and (2) load the read of the posts as normal.
