Spelling and Grammar Errors in Control file

Steps:

1. Open Ubuntu Software Center
2. Search for gcompris
3. Click the 'More Info' button

There are some spelling and grammar mistakes in the description text.
Second paragraph states "Language-oriented games now contain vocabulary for too many languages to list them heres. "
I suggest that it is changed to "Language-oriented games contain vocabulary for many different languages."

In the list of available boards in the next paragraph there is the line " . learning simple arithmetics"
This should read ". learning simple arithmetic"

The last line also has ". etc."
My opinion only, but I don't think we need that.
