[PATCH] Document a feature in the FAQ

[Daniel Shahaf]

Add a FAQ entry for the Blinkenlight UI's 'Force an immediate resync' feature.

I discovered the feature by accident, and didn't find it documented
anywhere.  I didn't mention the plans for SIGUSR1 "resync all accounts"
(from README) in the FAQ.

Also, in SubmittingPatches.rst, there are some places that use tabs for
vertical alignment (such as section (d) of the Certificate of Origin)
--- they should probably be using spaces.

+Can I force OfflineIMAP to sync a folder right now?
+---------------------------------------------------
+
+Yes, if you use the `Blinkenlights` UI.  That UI shows the active accounts
+as follows::
+
+  4: [active]      *Control: .
+  3: [  4:36]      personal:
+  2: [  3:37]          work: .
+  1: [  6:28]           uni:
+
+Simply press the appropriate digit (`3` for `personal`, etc.) to resync that
+account immediately.  This will be ignored if a resync is already in progress
+for that account.
