[PATCH] Add Templates Export this patch

This adds the ability to load templates into the body of the
email. When compose is called with '-T' flag, the default template
or the template with the name passed as value is used to populate
the body of the email.

There are two new configs options for accounts.conf: TemplateDir
and DefaultTemplate. Template Dir specifies the directory containing
the templates.DefaultTemplate specifies the template that is loaded
if no template name is provided.

Nice work. I've added some comments and have a couple of questions:

Should other commands e.g. reply or forward have a template
available as well? If so, then it could be a good idea to put some of
this logic in a lib file.

Also, could you add docs for the command in doc/aerc.1.scd?
Okay, so you mentioned this in the ticket and went with the easier
approach - but hear me out. If we put this into the composor and make it
work for replies, we can generalize this nicely by using golang text
templates. Then, the default reply template becomes something like this:

On {{.Date}}, {{.From.Name}} wrote:


I don't recall exactly how text templates work, but something like this.
The quote function would quote and wrap the original email at 72
columns, and the cursor() function would emit an empty string but would
magically record the current index and move the cursor there.
