Support also tickets with no cases

[Shai Berger]

The existing plugin forces all tickets to be linked to salesforce cases. This can be wrong both businesswise (some tickets have no case) and technically (e.g. if there are existing tickets in the Trac database before the plugin is installed).

The attached patch allows tickets not to be linked. Since it is hard to link a ticket once it exists, it requires that in this case the case-number will be explicitly set to "none".

Hello, sorry if it seemed I ignored this - I never got a notification email, or my email client sent it to the spam folder. Let me check it out...

Hm, I may have other changes, some of which may be improvements, that we made later. I mostly lost interest in this, having switched jobs, but if there's interest, I may be able to dig something up.
