use eclipse formatter for all projects

for all 6 eclipse projects:  configured to use formatter "eclipse [spaces-only]" and activated "format source code" as "save action"

This allows to have a consistent code formatting and only shows real changes in the future.

The formatter "eclipse [spaces-only]" was taken from project "owncloud-android".

As this PR changes many files, please accept fast. Or deny, if you don't like it. No content was changed at all, just formatting.
