Automatically (re)generate .factorypath

[nomis]

A Maven project shouldn't need to have every dependency filename stored in the .factorypath file in version control.

Entries referring to M2_REPO should be automatically created and updated if they are not present.

We keep trimmed down factorypaths in VCS, because by default undesired processors get enabled.
It's inconvenient, because we have to reset factorypaths after each Maven -> Update project.
This task could potentially make limiting processors "for everybody" (in VCS) even harder.

This has recently caused me problems with androidannotations because the .factorypath is never updated, so Eclipse was still using an older version.

I don't have the bandwidth to work on that for the time being. But if anyone wants to contribute a fix, I'd be happy to review it

So actually the factory path is updated when doing Maven > Update Project. In the following screencast, with automatic project configuration enabled, you can see the factory path being updated automatically :

I've deleted the .factorypath file and alt-f5 did not regenerate it.
