cvsps: use commitids (when present) to detect changesets Simplify core logic by no longer attempting to work around missing class attributes. Instead always generate the attributes and ignore the cache if the attributes are missing

hgweb, spartan: link from manifest title to changeset page

hgweb, spartan: add "URL breadcrumbs" This change adds a "URL breadcrumb" to the "title" of the pages on the spartan template. By title I mean the first line that is shown right below the page selection row, which shows the name of the page that is being viewed, along with some additional information. In doing so it standarizes those "titles" which now follow the pattern: URL breadcumb / page details

hgweb: add a "URL breadcrumb" to the index and repository pages The purpose of this change is to make it much easier to navigate up the repository tree when the hg web server is used to serve more than one repository. A "URL breadcrumb" is a path where each of the path items can be clicked to go to the corresponding path page. This lets you go up the folder hierarchy very quickly. For example, when showing the list of repositories in http://myserver/myteams/myprojects, the following "breadcrumb" will be shown: Mercurial > myteams > myprojects Clicking on "myprojects" reloads the page. Clicking on "myteams" goes up one folder. Clicking on the leftmost "Mercurial" goes to the server root. This "breadcrumb" also appears on all repository pages. For example on the summary page of the repository at http://myserver/myteams/myprojects/myrepo the following will be shown: Mercurial > myteams > myprojects > myrepo / summary This change has been applied to all templates that already had a link to the main repository page (i.e. gitweb, monoblue, paper and coal) plus to the index page of the spartan template. In order to make the breadcumb links stand out the some of the template styles have been customized.

merge: never do premerge on symlinks Simplemerge is not symlink aware and will never do the right thing on symlinks.

merge: make internal merge fail cleanly on symlinks Simplemerge is not symlink aware and will never do the the right thing on symlinks. It would read the symlink as a file and abort with 'No such file or directory' on dangling symlinks. Instead, internal:merge now simply fails to merge symlinks.
