[mylyn-dev] bootstraping on the latest Mylyn

Hi,

if you update to the latest Mylyn you will notice a hanging UI and a
busy disk on first task activation. This is due to the changes for bug
226618 that move context related state from the Eclipse preferences
store to a new location on disk. Depending on the number of task
activations and the size of the preference store [2] this can result
in the creation of several thousand files (which were previously held
in memory at all times).

This is a major change to improve performance. If the migration takes
insanely long on your system (more than 20 sek.) please let me know
and I will look into improving the feedback (right now there is none).
If you notice any regressions in regard to handling of editor restore,
cloning contexts and such please also let me know.

Thanks,

Steffen
