Remember flagged state when searching on moderation pages; Fixes #181
Finish off #489 for searching on some moderation pages

* Apparently flagged true form variable is carried over between tabs/refreshes so remove it when not on a flagged query
* Resolve incremental form variable by moving `isFlagged` into conditional
* Stray trailing comma in object fix
* Remove some dead code
* Some STYLEGUIDE.md conformance with missing braces and newlines, and some strict equality test *(still one left in this file but not testing there yet)*
* Tested non-flagged routes and checks okay

Closes #181
Change `placeholder` attribute for flagged items

Applies to #181, #489 and implemented in #491

Auto-merge ... confirmation of theory versus test results... this is a fix and generating a new refactor issue.
Force a couple of mustache options to always happen

* Very odd boog... dev had `Search Flagged Libraries` and pro had `Search Libraries` until I blanked out dev lib flags... then they matched. Force the text in along with the flag just to be sure. DOM duplication now appears to be related only to the logic issue at #492
