register: use full width, column widths, cleanup

Browse Source 
Refactored and enhanced the --width option used by register (and other
commands in future). register now uses the full terminal width by
default except on windows. Specifically, the output width is set from:

1. a --width option
2. or a COLUMNS environment variable (NB: not the same as a bash shell var)
3. or on POSIX (non-windows) systems, the current terminal width
4. or the default, 80 characters.

Also, register now accepts a description column width as part of
--width's argument, comma-separated (--width W,D). This adjusts the
relative widths of register's description and account columns, which are
normally about half of (W-40):

<--------------------------------- width (W) ---------------------------------->
date (10)  description (D)       account (W-41-D)     amount (12)   balance (12)
DDDDDDDDDD dddddddddddddddddddd  aaaaaaaaaaaaaaaaaaa  AAAAAAAAAAAA  AAAAAAAAAAAA

Examples:
$ hledger reg                 # use terminal width on posix
$ hledger reg -w 100          # width 100, equal description/account widths
$ hledger reg -w 100,40       # width 100, wider description
$ hledger reg -w $COLUMNS,100 # terminal width and set description width
