FEATURE REQ: bzr ignore + bzr -d ignore

[Jari Aalto]

This command is handy:

     $ bzr ignore '*.tmp'

so that the ./.bzrignore does not need to be edited by hand. but for
symmetry it would require equivalent remove/delete command:

     $ bzr ignore -d '*.tmp'

I'd rather not use '-r' because it's connotation is more --recursive
or --revno.

SIDE NOTE:

Has there been discussion about possibility to support regular
expressions as well? The command syntax would only need a modifier:

     $ bzr ignore --re '*.tmp'

and the ./.bzrignore would need a flag to indicate this nature. Say
adding 'RE' to the end of line:

    *.tmp
    *.bak
    \.[0-9]+$   RE
