problems with "&" in search string

[ollehints]

In detail search for specimens, if one selects reference to search for, and the reference contains '&', the search string gets truncated at so that only the first part of the string will be used. For instance, try to search for specimens that are mentioned in reference "Hints, O. & Nõlvak, 2006".
Possibly the same problem occurs elsewhere in search boxes (reference.reference is the main place where & frequently occurs).

'&' can now be escaped by
