Push1.0.0 release blog and updates

updates for the 1.0.0 release of the UPS, as well as adding an announcement post that summarises the release.

@abstractj for docker, can you tell me where to link ? 
@corinnekrych do you have a blog post for more details on swift? (does not need to be specific to push - everything that points to AeroGear and Swift would be a nice teaser for more goodness for the AeroGear team).



## Download of the UPS bundle.
Once the thing is release, the files in here:
http://people.apache.org/~matzew/aerogear-unifiedpush-server-1.0.0.Final/

will be uploaded to the github rleease. the site, as discussed, will simply point to LATEST (of GH), while using the latest version string (1.0.0.Final in this case)
