In some languages it's conventional not to insert a thousands
separator in numbers that are four digits long (1000-9999).
Rather than copy-paste the custom code to do this between 13 files,
introduce another option and have the base Language class handle it.
This also fixes an issue in several languages where this logic
previously would not work for negative or fractional numbers.
To implement this, a new option is added to MessagesXx.php files,
`$minimumGroupingDigits = 2;`, with the meaning as defined in
<http://unicode.org/reports/tr35/tr35-numbers.html>. It is a little
roundabout, but it could allow us to migrate the number formatting
(currently all custom code) to some generic library easily.

I removed comments that merely repeated the location of the class being
tested. There are other tests in this directory that don't have a
corresponding class and need further investigation.

CLDR provides translated language names. They are useful for showing
names by themselves in menus and lists, but it's often problematic to add them
to Russian sentences, because they need to be declined, so a message like
"This page is not available in the $1 language" is hard to localize.
This patch adds new cases for Russian -
"languagegen", "languageprep" and "languageadverb".
(The last one, as its name says, it's not actually a grammatical case,
but a transformation to an adverbial expression.)
This covers most of the needs for language names that MediaWiki supports.
