Do some code cleanup/optimizing (including bugfix)

Do some code cleanup and optimizing, and fix a bug where the script will
always return exit code 1 if LETSENCRYPT_COMMAND_AFTER wasn't defined.

The bug was caused by this last line in the script:

[ ! -z "${LETSENCRYPT_COMMAND_AFTER}" ] \
	&& eval $LETSENCRYPT_COMMAND_AFTER

... and has been fixed by putting the "eval $LETSENCRYPT_COMMAND_AFTER"
line into a real "if" container so that it doesn't affect the exit code
of the script when LETSENCRYPT_COMMAND_AFTER is undefined:

if [ ! -z "${LETSENCRYPT_COMMAND_AFTER}" ]; then
	eval $LETSENCRYPT_COMMAND_AFTER
fi
