[mylyn-integrators] change to suppress incoming notifications for attributes in custom sections

[Sam Davis]

Hi,

We have just merged a change to Mylyn's incoming notification mechanism
which suppresses notifications on changes to most attributes that have no
kind. Connectors that display attributes with no kind in a custom section
should ensure that the attributes in those sections have a kind. Otherwise,
users will not be notified when those attributes change. See
https://bugs.eclipse.org/bugs/show_bug.cgi?id=486145 for details.

Cheers,
Sam
