Update `mail-check` script to notify the user both of newly arrived
mail, and in case he has to enter his password to sync the mail.
HACK the paths and ways of finding out if passwords can be decrypted are
static and only applicable to my set up. This needs to be completely
revised and newly approached.
Fixed running the hooks for `mail-check`. Command (or variable?)
substition prevented the hooks from running completely beforehand, so I
moved them to a separate function with the option remaining to call a
custom script for them through environment variables.
Ideally the env vars (`MBSYNC_PRE` and `MBSYNC_POST`) should only point
to a single script each, as more involved commands will presumably fail
to execute correctly when whitespace substition is involved.

Added `mail-searchcontacts` script, which uses notmuch to search for all
contacts of the mail database.
Can be invoked without any arguments to list *all* contacts of the
dataase in descending order of message count.
Otherwise, it will filter known contacts, first by prioritizing the
'from:' field, and otherwise by searching through the whole database for
the keywords passed in.
It will also re-format the results so that the list consists of
tab-delineated 'mail name' rows. If there is no name, the row will only
contain the bare e-mail address. This format is best accepted by aerc,
for which the script is written.
aerc uses the contacts script for its address completion in editing
e-mail headers.
Renamed `checkmail` to `mail-check` to fit the naming scheme of
`mail-[action]` for mail scripts, to better be able to group them in the
shell.
