Fix Collapsed Topics and Columns course formats.  Requires V2.6.1.3 of Collapsed Topics and V2.6.1.1 of Columns.

Hi Julian,

Not the complete refactoring fix, but one that works and is simple.  Requires testing with versions of CT and Columns from:

https://github.com/gjb2048/moodle-format_topcoll/tree/MOODLE_26 - V2.6.1.3 - provisional.
https://github.com/gjb2048/moodle-format_columns/tree/MOODLE_26 - V2.6.1.1 - provisional.

If all is well, I'll release as fix works outside of Elegance theme.

Cheers,

Gareth
