Add dcron.

There doesn't seem to be a way to autostart the daemon on boot (unless
we directly modify the boot script). Assume the user will do that
himself by adding to ~/config/settings/boot/.

crond needs to be told where to store the crontab and cronstamps file,
and where to read the cron files. The default values are non-existing
folders in /var and /etc (just creating those is ok, too).

+SUMMARY="dillon's lightweight cron daemon"
+DESCRIPTION="
+This is a continuation of Matt Dillon's beautifully minimalist dcron. At first
+I had written a fork (yacron), but Matt has handed over maintainership of the
+main dcron branch, so all of yacron was merged into dcron 4.0.
+
+The biggest changes in v4.0 are syslogging and a variety of anacron-like
+features. If you use this version of dcron, you shouldn't have any further need
+for anacron.
+
+More specifically, dcron can now:
+* log to syslog or a file
+* email job output to a remote addresses, instead of the local user who owns \
+	the job (so it works with lightweight mail handlers like msmtp, which \
+	don't route mail to local users).
+* replace sendmail with any other script to which all job output should be piped
+* various crontab syntax extensions, including @daily and @reboot and more \
+	finer-grained frequency specifiers. See manpages for details.
