Exclude spaces and maybe tags from SUMMARY in iCalendar export

[Tassilo Horn <tassilo@member.fsf.org>]

Hi all,

I've just discovered the iCalendar export and use that to have a
visually appealing read-only agenda in KOrganizer.  Basically, the
export seems perfect except for one thing.

When I have an org entry like

* Test                                           :some:tags:here:

the corresponding VEVENT will have the whole org heading including the
spaces and the tag string as SUMMARY (unless the entry has a SUMMARY
property).  Having the tags there might be ok (although by default they
are also set as CATEGORY), but the spaces between the heading title and
the tags should be compacted.

Appended is patch that does that when not `is-body'.

Bye,
Tassilo
