[Pre-release] v0.2.1-alpha.6+12

This is the release candidate 1 of Thunder for v0.2.1+12! This nightly fixes some issues introduced in the last pre-release. No more new features will be added in the nightlies until the next general release.

Be fully prepared to know that these pre-release versions may contain major bugs which could cause Thunder to crash or behave unexpectedly.

These are some of the changes that have occurred since the last pre-release. For things to test, I would suggest all the usual actions, and all the new features/changes which have been introduced in this nightly:

• Fixed issue where image viewer actions were being shown behind system navigation bar
• Added more details and information to the debug settings page, and added confirmation dialogs for each debug setting
