Fix test output for updated gitdiffs help and web template cleanups

Do not abort with inotify extension enabled, but not supported by the system. And remove the "native support is required" message which is generated at an inappropriate location and is printed more than once when using 'hg status'.

Enhance gitdiffs help text

Kill trailing whitespace in templates

graphlog: move functions around, eliminate helper function Makes it easier to read all of the code.

graphlog: split the actual DAG grapher out into a separate method This allows extensions like pbranch to use asciigraph() to graph dependencies for patch branches, but could be used for basically any DAG.

graphlog: rename some vars prior to refactoring

graphlog: make some comment lines more like others in punctuation

patchbomb: fix indentation

patchbomb: move exportee class to top level As suggested by djc.

ui: log non-interactive default response to stdout when verbose This allows test scripts that feed their output into documentation to properly show the session as it would appear to an end-user.

export: fixed silent output file overwriting hg export -o outfile 1 2 3 4 had the same effect as hg -o outfile 4 This was caused by opening with 'w' instead of 'a'. This only occurs when the filename pattern resulted in ambiguous patch filenames.

merge bookmarks

bookmarks: Test if rebase works with bookmarks Add a test that tests if rebase works fine with bookmarks.

bookmarks: Use dirstate to determine the current node in addchangegroup Using the changectx might result in a lookup error during the strip command. Thefore we use the current dirstate to get the parents of the working directory.
