Add support for different sort order of dashboard tiles

[gene1wood]

The SSO dashboard currently sorts all the tiles on the dashboard by their name.

This results in an entry like The Hub being sorted in the T's.

Either add some logic to detect prefixes like The and strip them before sorting

or add support to assert in apps.yml the string that should be used for purposes of sorting. The idea would be in the absence of this setting in an apps.yml entry, the name of the application would be used for sorting (as it is today), but if this new field was present, that value would be used instead. In the case of The Hub this new field, e.g. called sort_name, would have a value of Hub.
