Patch the make_rst.py utility to handle specially operators with '<'

When generating rst files from xml class reference, unknown references
to operators were generated, as something like:

:ref:`operator <<class_Vector2_operator_lt_bool>`

was rendered in html as:

operator ( Vector2 right )

-it just needed escaping.

The small addendum checks for operator names containing '<' and
substitutes it with '\<', escaping at rst level and generating
instead the right rendered html:

operator < ( Vector2 right )

This affected mostly the reference pages of the VectorX family of
classes. If in the future more types need escaping, a more
general solution will be needed.
