Defect/Feature description

With the advent of geteduroam (and the potential for similar apps that may use CAT's data), there is a need to improve the user experience when trying to "discover" their identity provider in a user interface. Research in the RA21 project has shown that end-users approach free-form search interfaces for their home institution in different ways and often type the form of their institution name they're most familiar with. This may not always be the institution's full or proper name as recorded in CAT (and may not even be formally adopted by the institution).

For this reason, we should support the recording of well-known short-form names in addition to the current institution name. For example "UCLA" in the case of the "University of California, Los Angeles"; "MIT" for "Massachusetts Institute of Technology"; "UniVen" for the "University of Venda"; etc.

Having such an extra field would mean that an end-user search for either "UCT" or "Cape Town" should lead to the same "University of Cape Town" identity provider, being more in line with user expectations.
