qseries: add --edit option for editing .hg/patches/series

Users should never touch any files in .hg - with .hg/patches/series being an
exception for some common operations - such as reordering patches.

This introduces an option to edit the series, and we can thus again tell the
users that they should never touch any files in .hg.
