LegendKeeper 0.15.2.1

The "Mentioned In" block has been upgraded to "Backlinks". The Backlinks block more accurately catalogs @-mentions of an element elsewhere in your project.
- You should expect your "Mentioned In" results to change a bit. They will become technically more accurate. It will no longer link "Unlinked mentions"; we'll consider adding that as a feature in the future.
- You may need to hit the "Rebuild Indexes" button under Settings > Project > Advanced, after which your entire project will be reindexed.
Backlinks now show and link directly to the tab where the link is.
- Backlinks only supports pages, but has the infrastructure required to report pins, board cards, and other kinds of links in the future.
Fixed long-standing bug causing some pages to skip search indexing.
Added "change image" button to image blocks in properties.
Templates should no longer show up in Tag Index blocks.
Fixed bug causing settings menu to close itself on first tab click.
Public view now respects Sidebar: Open/Closed default setting.
Disabled unintended ripple effect on tabs.
Various bugfixes and style tweaks
