OpenVPN wizard: remove incorrect legacy text

(legacy, ipsec) vpn_ipsec.php replace glyphicon glyphicon-remove with fa fa-trash text-muted (again, original in https://github.com/opnsense/core/commit/87014246c03c1697cd1836c973435bd85f8e9b80)

Added tooltip to show description of schedule and fixed editing capabilities of
schedules from page firewall_rules.php.

Tooltip shows description of alias.

changed file type

The way the code is currently set up it will never truly rebuild the
routing table, so old gatway monitoring host entries may linger in
the system until properly rebooted or fully reconfigured.  But all
in all, routes are now skipped properly if no monitoring is needed.
