client: support multi-line print for long values

Browse Source 
The generic proxy property display was limited to a width for names/value
which makes the output look nice and uniform, but will cut off any values
which are longer than this limit.

This patch adds some logic to detect this, and continue displaying the
value on the next line.

The width arguments were also updated to be unsigned, which allows checking
the length without a cast.
