Special characters in text field are not scaped when events or todos are exported. For example, ',' in the description field are send literal. According to rfc2445 section 4.3.11 there are some characters which must be scaped or quoted. This patch tries to solved this problem.

It is the simple patch to prevents the segfaulting of horde on ical with
spaces in the begin:vevent etc lines. (just \W\w replaced by \S if I
remember well at one place..)
The second patch is for getting rid of some php5 warnings when it
encounters the array_merge() in setParameter(). (only a simple cast to
an array).
