Test plan for the various cases of interaction between standalone apps and kontact:
1) start kontact, select "Mail".
1a) type "korganizer" -> it switches to korganizer
1b) type "kmail" -> it switches to kmail
1c) type "kaddressbook" -> it switches to kaddressbook
1d) type "kmail foo@kde.org" -> it opens a kmail composer, without switching
1e) type "knode" -> it switches to knode
1f) type "kaddressbook --new-contact" -> it opens a kaddressbook contact window
1g) type "knode news://foobar/group" -> it pops up "can't resolve hostname"
2) close kontact. Launch kmail. Launch kontact again.
2a) click "Mail" icon -> kontact doesn't load a part, but activates the kmail window
2b) type "kmail foo@kde.org" -> standalone kmail opens composer.
2c) close kmail, click "Mail" icon -> kontact loads the kmail part.
2d) type "kmail" -> kontact is brought to front
3) close kontact. Launch korganizer, then kontact.
3a) both Todo and Calendar activate the running korganizer.
3b) type "korganizer" -> standalone korganizer is brought to front
3c) close korganizer, click Calendar or Todo -> kontact loads part.
3d) type "korganizer" -> kontact is brought to front
4) close kontact. Launch kaddressbook, then kontact.
4a) "Contacts" icon activate the running kaddressbook.
4b) type "kaddressbook" -> standalone kaddressbook is brought to front
4c) close kaddressbook, type "kaddressbook -a foo@kde.org" -> kontact loads part and opens editor
4d) type "kaddressbook" -> kontact is brought to front
5) close kontact. Launch knode, then kontact.
5a) "News" icon activate the running knode.
5b) type "knode" -> standalone knode is brought to front
5c) close knode, type "knode news://foobar/group" -> kontact loads knode and pops up msgbox
5d) type "knode" -> kontact is brought to front
