Improved mobile layout for the image picker on Firefox for Android.

On Firefox for Android, reblogging is now one tap: small reblog badges appear directly over each image on a reddit post — no more digging through the ⋮ menu. Desktop behavior (right-click, toolbar picker) is unchanged.

Picker now supports selecting multiple images before reblogging — tap to select, then confirm with a single "Reblog N selected" button, instead of one image per popup open. Also fixed thumbnail sizing on Android, where the picker was constrained to a tiny fixed-width layout meant for desktop; it now uses the full screen width with larger touch targets on touch devices.

What's new in 0.2.0:

• Added Firefox for Android support. Since Android has no right-click menu, tap the reblogr toolbar/menu icon on a reddit.com post page to open a picker listing the post's images — tap one to reblog it.
• The picker now shows a clear empty state if it can't find any images on the page, instead of silently doing nothing.
• Minor description cleanup.

Desktop right-click "Reblog to Tumblr" still works exactly as before.
