New version of emacs-eclim & completion setup stuff

[fred-o]

Hi, I've reworked the completion code in emacs-eclim, and correspondingly updated the version in cabbage.

Also, an older change which fixed indenting of certain methods in java code seems to have snuck in as well.

Could you rebase the branch, to remove your local merge commits?

Thanks very much for the work! :heart:

[fred-o]

Rebased!

@jone noticed that this change executes code for all installs that have the completion bundle enabled. I'm not sure if we should set cabbage-java-use-eclim to nil and then set it to t in the bundles, that actually make use of eclim. This would mean, that if I don't have the java-bundle (or other bundles using eclim) enabled, it won't enable eclim within the completion bundle.

@fred-o what do you think?

[jone]

If the eclim sources have a decent fallback we could also use separate completion frameworks (e.g. auto-complete-eclim and company-mode-eclim).

Sorry I forgot to follow up on this. I guess we could make nil the default for cabbage-java-use-eclim, but I suspect it could be tricky to enable it automatically in other bundles as we would be very dependent on the order the bundles are loaded. Better then to have the user enable eclim exlicitly.

@fred-o could we detect of a working eclim installation is present? If so we can set the variable to t if an installation exists and use nil otherwise.

sorry, hit the wrong button :neckbeard:

[fred-o]

@senny I think it'd be tricky to detect the installation correctly.

so I think we need to find a solution to make it nil by default and enable it from the bundles. I think (defvar) for the default and (setq) to override should work.
