Subject: [PATCH] (dev/core#4303) Allow {htxt} guard to accommodate variable ID

Before
------

`{htxt}` guard works with static IDs (`{htxt id="abc"}`)

After
-----

`{htxt}` guard with with variable ID (`{htxt id=$abc}`)

Comments
--------

As discussed in dev/core#4303, one relevant use-case comes from `CustomField.hlp`.

In my copy of universe, there's a similar construction in
`nz.co.fuzion.entitysetting` (`entitysettingscommon.hlp`).
