Update screenshots in documentation for Bulk Move with Versions/Components field

There is a screenshot in our docs of Versions and Components in Bulk Move that is now out of date (it was actually out of date before): http://confluence.atlassian.com/display/JIRA/Modifying+Multiple+%28%27Bulk%27%29+Issues#ModifyingMultiple%28%27Bulk%27%29Issues-bulkmove

It needs to be updated to reflect the new interface given to users when mapping version and component fields.

Tokes completed a 3 day spike of JRA-8248 - Bulk Move components and versions

He established that we should be able to implement a feature which allows mapping old project values (for Components, Versions) to new values using multiple edit controls and a simple name matching strategy to preselect the smart choice. This work will be completed in a future iteration.
