Increased jenkins base version in pom and removed a few
errors that popped up in eclipse as a result.  Also added .gitignore to
prevent eclipse metadata files from getting into repo.
Added config-trigger block to configure-entries.jelly.

This was necessary because saving the MasterProject was removing all of
the downstream triggers in any of the jobs contained in the master. All
subjobs were loosing their "build other projects" configuration.

Adding the config-trigger block sent that data along when saving.
Added method to filter out disabled jobs before execution to prevent
infinite loop.
Added include for makeDisabled.jelly so that the enable/disable button
is shown on the main project page.
