Updater V1 changes

[frauzufall]

• imagej-scijava-plugins-uploader-webdav: 0.2.2 -> 0.3.1
• imagej-ui-swing: 0.22.0 -> 0.23.1
• imagej-updater: 0.9.3 -> 0.10.1

This is the first stage of a new updater - a version which checks the Java support of our HTTPS certificate and changes the URLs of update sites depending on that. It can also handle changes to URLs on the list of available update sites (in the original version these changes were ignored). Changes to an activated update site URL always have to be approved by the user before they are applied.

I updated this PR to the newest updater version (though we could make a new release from the recent changes, but I wanted still test the master one more time before doing that). I added apache-httpclient, apache-httpcore and jackrabbit-webdav to the dependency management, they are needed by imagej-plugins-uploader-webdav. Not sure if I have to exclude commons-logging or how exactly the logging dependencies have to be handled.

Since this is the first time I am adding managed dependencies to pom-scijava, it would be great if someone could have a closer look if what I do is correct.
