[WIP][v1.0.4] More customizations

Planning on adding a bunch more customizations in this update. The plan is to hopefully add settings to allow full customization of fonts.

This update will also add search to the settings page. The app has accumulated so many settings and it's getting hard to discover them all. Hopefully making settings searchable will help with this.

Changes so far

• Added new themes suggested by users
• Added search to settings
• Added setting to change the global font of the app. Current options are default/system, roboto, roboto serif and open sans
• Added setting to change the upvote/downvote color
• Added setting to use volume buttons to go to the next/previous top level comment
• Added setting to only show top level comments by default
• Added setting to open links in the external browser
• Added mark all as read button
• Fixed some rare crashes

Update

Making a release soon.

Update 2

Thanks for the quick bug reports. I'll do another release to fix the bugs soon.
