* mu4e/org-mu4e.el (org-mu4e-store-link): Add capture template keywords

For other email links (e.g., wl, mh, gnus), a number of keywords are
defined in org capture templates.  This makes these keywords available
for use in captures from mu4e.

Add different face attribute for the mode-line

There is an additional face attribute for the mode-line.
Updated html export to org v8 standards

Replaced use of org-export-string with org-export-string-as to match
updated org coding standards.

This specifically addresses issue #391
mu-cmd-server: fix compilating warning (BSD_SOURCE)

Fedora-21's gcc started complaining about this
mu-threader: debugging for some reported problem in find_or_create
mu-msg-crypto: give better error when gpg is not found

also fixes some other warnings
mu.1: mention --nocolor. Fixes #485
mu4e: add note about completing-read / helm to the FAQ (#286)
split off `org-old-mu4e.el' for backward compatibility

For now this is just a copy of org-mu4e.el (which requires org-mode
8.x), but the expectancy is that they will diverge.

Fix encrypted multiparts and attachments indexing

Pull request #483 does not handle encrypted multiparts properly.  It
used to just verify the signature and not process the parts of the
multipart.  This commit resolves this issue.

Additionally it did not index attachments properly and in the case of a
multipart directly containing more than one multiparts resulted on non
unique indexing of attachments/parts.  This commit resolves this issue
as well.
