JavaScript .replace always magically processed $$ $& $' $` in replacement
strings and thus displayed subject lines incorrectly in the graph view.
Instead of regexps and .replace we now just create the strings the right way in
the first place.
All implementation in graph.tmpl are the same. It can still be overriden if
necessary. There is no clear reason to keep it separated from mercurial.js.
This allow safe caching of the pages by the browser and still display the right
amount of elapsed time upon page refresh.
If javascript is disabled, absolute time is displayed, leaving it readable.
All the templates have been updated.
Remove the `install_package_data' subclass of `install_data' and use
the `package_data' functionality provided by distutils instead. As
package data must be located within the package directory, the data
files are now generated in the build directory.
To simplify the functionality of this change, the top-level `doc' and
`templates' directories have been moved into the `mercurial' package
directory.
