Bug 31062: Change description of QOTD tool in tools-home

This patch changes the name and description of the QOTD tool in order
to make them more consistent with the other tool names and descriptions.

To test:
1) Go to Tools
2) Read the QOTD tool name and description, make sure they make
   sense and that there are no typos
3) Test the link to make sure it goes to the tool
