Add a tab to the Silverstripe cms from witch mobile web app capabilities can be managed.

1. Extract the folder in the root of the silverstripe installation.
2. Run a /dev/build?flush=all

if the content of the web app config tab looks crooked in the cms, you need to run a ?flush=1 in the cms. It is possible that the included templates are not yet found.

note: Splashscreens like the ipad-retina-portrait and ipad-retina-landscape can be bulky in size, sometimes 5mb in size, you need to check the server settings if you are not allowed to upload files bigger than 2mb. This can be done in the php.ini file. Change the value of upload_max_filesize = 2M to upload_max_filesize = 5M or more. Sometimes you'll also have to change the value post_max_size.
