Handle long strings in usage

[jontejj]

Includes long:

• descriptions
• names
• meta descriptions
• default value descriptions
• valid value explanations

Replace each newline with a newline and enough spaces to fill up the left column. Split up long lines, Use BreakIterator.getLineInstance()?

As some tests concerning file arguments found out, breaking up default value descriptions and valid value explanations may be very bad. For example, breaking up:

Default: /Users/user/maven_projects/softhouse.se/jargo/jargo/.

Into Default: /Users/user/maven_projects/softhouse.se/ jargo/jargo/.

means that an invalid file path is produced, not a good thing.
