Fixing svn-push, jQuery UI and load_plugin_textdomain

This Pull Request resolves 3 issues.

The `svn-push` command was creating problems related to excluding some files, so I only exclude for real the `.git` folder from the `git ls-files`.

I think that in the future this could be translated to a more solid piece of code, I think it could be a Python, Ruby or Node terminal module.

It has room for improvements for sure.

@luancuba when you created the jQuery UI you downloaded the file and shipped with the plugin which in this case is not necessary because it's just the base-theme for the jQuery UI, so I changed it to the Google CDN URL.

Check out that this only applies for smaller things.

When I created the files in the first place for the plugin they were misplaced without the `textdomain` in front of them.

As WordPress [`load_plugin_textdomain`](https://codex.wordpress.org/Function_Reference/load_plugin_textdomain) uses the textdomain on the files we need it on our files too.
