Format content using JS after the page loaded

[fmido88]

The problem:
Some content which displayed in the page not passed through format_text() or format_string() so it will remains in the raw form with the tags {mlang xx} something {mlang}
(eg. breadcrumb, report tables, headers, ...)

Solution:
Using js module to alter the data and filter all using ajax request

New problem:
The filtration take a bit after the page loading but it works

Better solution:
Do the whole filtration process with js without rely on Ajax request

I'm sorry, but I'm not merging this pull requests. Anything coming from from Moodle to the browser (both as HTML, and as AJAX values) should apply the filters correctly. This is just a band-aid to work around badly coded themes, plugins, etc. So we would be masking the bugs, instead of pressing the developers to fix them.

As I said, this doesn't belong in the standard filter_multilang2 plugin. You are of course free to apply the changes in your local copies 😄
