Feature request: support short_name as alternative name

[hbruch]

Currently, short_name is imported:

photon/website/import.py

Line 44 in e03b44b

name->'short_name' as short_name,

but not used in searches.

E.g. searching for NVBW Stuttgart returns no results (n4756096906#7 changed alt_name to short_name).

Is there a reason why it is excluded? Would it have negative impact on search results or would a PR be welcome?

In principle it is okay to include short_name. However, generally speaking, I wonder if we wouldn't want start making alternative names to be included configurable.
