Supported Eclipse versions in JMC 7.1.0.

[Mario Torre]

Hi Marcus,

We need to keep in mind that downstream packaging ability if we move
upward will be greatly reduced. I second we should support a minimum
version. We should try to move things slowly. I understand that this
only practically affect only the RCP application, but this is how JMC
is distributed in Fedora for example, and will likely be the case for
all the Linux distributions.

Having the lowest baseline does not mean we need to build with that by
default, I would be ok if upstream picks the latest Eclipse at any
given release time. To consider my pain specifically, 7.0 is not yet
officially released and it's the case that 7.1 will likely be released
shortly after that. If we change the defaults between 7.1 and 7.0 we
are asking for a platform upgrade in less than a month or so.

Cheers,
Mario

However, if we were to support the 4.8.0 platform, we'd need to build the plugins against the 4.8.0 platform then, right? Doesn't that contradict to your first proposal?
