Bottom bar labels should adapt to width change better

[AdamK]

Bottom bar label texts were created having in mind 80 column mode. Today, we usually have more then 80 columns.

With 80 colums restriction they are short and ugly, especially in languages other then english.

For each column where should be two text instances for each label:

• short (as of today, for 80 columns and less)
• long

The rule should be:

• if long text fits: use long text
• else, use short text.
