Add ColumnFormatter/StringUtil classes for text output
The ColumnFormatter class will simplify output of column-oriented text
for SSH commands like ls-groups and others (including HTTP counterparts)
that may print user-supplied text that can contain tab and newline
characters that would screw up scripts using these commands for
automation. To deal with this, all text output is subject to C-style
escaping of all non-printable characters. The escaping in done in the
new StringUtil class.
So far this new functionality is only used by the ls-projects command
when the project description is printed. The escaping method used there
previously only took care of newline characters.
