/*
Whether to start a new konqueror or reuse an existing process.
First of all, this concept is actually broken, as the view used to show
the data may change at any time, and therefore Konqy reused to browse
"safe" data may eventually browse something completely different.
Moreover, it's quite difficult to find out when to reuse, and thus this
function is an ugly hack. You've been warned.
Kfmclient will attempt to find an instance for reusing if either reusing
is configured to reuse always,
or it's not configured to never reuse, and the URL to-be-opened is "safe".
The URL is safe, if the view used to view it is listed in the allowed KPart's.
In order to find out the part, mimetype is needed, and KTrader is needed.
If mimetype is not known, KMimeType is used (which doesn't work e.g. for remote
URLs, but oh well). Since this function may be running without a KApplication
instance, I'm actually quite surprised it works, and it may sooner or later break.
Nice, isn't it?
If a profile is being used, and no url has been explicitly given, it needs to be
read from the profile. If there's more than one URL listed in the profile, no reusing
will be done (oh well), if there's no URL, no reusing will be done either (also
because the webbrowsing profile doesn't have any URL listed).
