Formatting fixup for 'mythbackend --printsched'

[Nick Morrott <knowledgejunkie@…>]

A formatting fixup for the --printsched console output. ChID was not justified causing all sorts of issues with alignment of subsequent column headings and data, making the information very hard to read quickly.

This patch aligns all data, and adds a new column of CallSign?.

Example output pre-patch:

--- print list start ---
Title - Subtitle                    Chan ChID Day Start  End   C I  T N   Pri
