Plugin should detect an outdated client build jar and replace it

Original issue 4 created by codenameone on 2012-02-05T19:06:58.000Z:

The plugin should check the size of the file which will likely always be different against the local size (no need for MD5 for now) and just update the file. Optionally prompting the user for confirmation.
Bonus points if the plugin can detect an out of date build.xml and update it too (we can add a "version" comment at the beginning of the build.xml file).
