Reword Administration Rights UI to remove the mention of Space

If you go to the global Administration > Rights you see the following options with checkboxes:

• Prevent unregistered users from viewing pages, regardless of the page or space rights
• Prevent unregistered users from editing pages, regardless of the page or space rights

Given we no longer use the term “space” we might want to adapt the text to:

• Prevent unregistered users from viewing pages, regardless of the page rights
• Prevent unregistered users from editing pages, regardless of the page rights

Prerequisites

Before starting your task familiarize yourself a bit with XWiki. You can see it in action in the Playground, so you should create an account there and test it a bit.
Your task might involve actions or applications that are not available on the Playground, so make sure you download and install the latest version of XWiki.

For questions you can always use the Forum or the IRC channel, see http://dev.xwiki.org/xwiki/bin/view/Community/Discuss

Try to reproduce the issue described by the task. You should use your browser's Developer Tools to identify and test your solution.

Once you have reproduced the issue presented in the task, it's the time to identify the location where it needs to be fixed in the code.
The sources are available at https://github.com/xwiki/xwiki-platform . You should be familiar with using Git locally or you might be able to commit your changes from the GitHub interface.

The task will give you hints about the component where the code with the problem is located. Identify the file, make the changes and submit a Pull Request for mentors to approve and close the task. Don't forget to add screenshots with before and after your changes.

Objective

Find the problematic translation and see if this can be modified or deprecated and replaced with another translation key. You might need to create or reuse a page dedicated for Translations.

Requirements

• Knowledge of XML
• Knowledge of Git
• You will encounter concepts like Data Model, Apache Velocity, Localization module etc. but you don't need to be familiar with them in advance

Expected Outcome

• Pull Request on the https://github.com/xwiki/xwiki-platform repository with the solution
• The summary of the Pull Request must have a first line matching the JIRA issue following by a colon and then the title of this issue
• Following best practices defined at http://dev.xwiki.org/xwiki/bin/view/Main/WebHome
