[WIP][v0.1.57] Filter everything

This update aims to add comprehensive filtering rules, allowing users to filter by almost any criteria.

This is the last core feature that will be implemented before the v1 release.

Changes so far:

• Add filter by keyword, community name, instance name or OP's name
• Support filtering using regex rules or regular string matching
• Filter posts by their primary content type (NSFW, link, image, video, etc)
• Add Card2 layout. This card layout puts the image in the middle of the card instead of at the top or bottom
• Change relative time to be shorter.
• Add setting to use title styles for post items
• Switch to material you text fields in some places
• Fixed a bug where dividers between comments would sometimes disappear
• Add setting to change global font size
• Change swipe to vote to toggle the vote
• Fixed a bug where certain links would not render properly
• Fixed a bug where tapping on multiple posts at the same time can cause weird behavior.

Update

I am going to be making a release tonight unless something goes horribly wrong. I still have like 5 more user requests to work through. If I end up not having time to implement it tonight then your request will be in the next update.

Update2

Tested the app for an hour. The app seems stable enough for a release but I have to head to bed. I'm going to do a partial release and finish up in the morning.

Update3

I keep finding more bugs. We are on v0.1.56 now. I think we are finally good for a release. :hopium:

Update4

I lied. Found more bugs. v0.1.57 now.
