util: kill Python 2.4 deque.remove hack

summary: add a phase line (draft, secret) to the output The number of draft and secret changesets are currently not summarized. This is an important information because the number of drafts give some rough idea of the number of outgoing changesets in typical workflows, without needing to probe a remote repository. And a non-zero number of secrets means that those changeset will not be pushed. If the repository is "dirty" - some draft or secret changesets exists - then summary will display a line like: phases: X draft, Y secret (public) The phase in parenthesis corresponds to the highest phase of the parents of the working directory, i.e. the current phase. By default, the line is not printed if the repository is "clean" - all changesets are public - but if verbose is activated, it will display: phases: (public) On the other hand, nothing will be printed if quiet is in action. A few tests have been added in test-phases.t to cover the -v and -q cases.

hgweb: also display changeset bookmarks in file log (style=paper) There already are branches and tags in file log, now let's add what's been missing: bookmarks. Also, since coal borrows this template from paper, this change is effective for coal as well.

tests: test branch/tag/bookmark display in test-hgweb-filelog.t Displaying branches, tags and bookmarks is an obviously important feature of hgweb and should be tested a bit more than not at all, so let's add a branch, a tag and a bookmark to the test. With this change it's evident that the default style (paper) doesn't show bookmarks in filelog. Future patch will fix this.
