Fixes for comments on push'ed code:

1. MultiRangeInlineEditor.js: simplified conditional, as requested.
2. ScopeManager.js: move function getResolvedPath before its use, to make JSLint happy.
3. QuickEdit/main.js: move functionName null check to calling routine for cleanliness.

Things not yet done:

1. QuickEdit/main.js: consolidation of fallback paths.
2. QuickEditHelper: communication between extensions.  Short vs. long term solutions.
