Make "hg log --style=changelog > changelog" work (issue338) Style files in templates/ now take precedence over current directory. This can be overridden with --style=./changelog if really neeeded. Added test for issue338.

Clarify precedence for template/style in commands.show_changeset(): Display format will be the first non-empty hit of: 1. option 'template' 2. option 'style' 3. [ui] setting 'logtemplate' 4. [ui] setting 'style' If all of these values are either the unset or the empty string, regular display via changeset_printer() is done.

add remoteopts to bundle command

factor opts: remote repo access options

factor opts: --dry-run option

factor opts: walk options

factor opts: move globalopts to a more logical place we will put other options at the same place

mq: raise util.Abort instead of using sys.exit(1)
