[sakai2-tcc] Cleaning up versions in Jira

[David Horwitz]

Hi All,

As discussed in LA we suggested getting rid of the x versions, so unless 
I hear otherwise I will archive the following versions:



- 2.6.x
-2.7.x
-2.8.x

Archiving means that issues that where tagged as affecting or fixed in 
those versions will still display this, however those versions will no 
longer appear in the dropdowns.

I would also suggest we archive the 2.5 versions:
2.5.0
2.5.1
2.5.2
2.5.3
2.5.4
2.5.5
2.5.6


Any objections?

Regards

David
