Make the HTMX object available in templates as a global context variable

[edmondchuc]

For example:

from flask_htmx import HTMX

htmx = HTMX(app)

Now in Flask's Jinja templates, a htmx variable is available. This is useful for such cases where conditionals are required to render certain blocks of HTML in the Jinja templates.

{% if htmx %}
<div id="app" hx-swap-oob="true">...</div>
{% endif %}

This is useful when paired with using Jinja's include tag and htmx's hx-boost and hx-swap-oob attributes.
