convert: hg.clonebranches must pull missing parents (issue941)

qrecord: add tests

qrecord: record complements commit, so qrecord should complement qnew Also there is an idea flying around to create something that will complement qrefresh: - maybe 'qammend'? or - 'qrefresh --interactive'? If we settle on '--interactive', then it would be conveniet to add this flag to 'commit' and 'qnew' as well.

Remove unneeded "import os.path"

send conservatively capitalized HTTP headers

demandimport: handling new relative imports Mercurial does not work on python2.6 because __import__ takes an additional argument called level. This patch merely calls the built-in __import__ when level is passed.

hgweb: move HTTP content types out of header templates This removes the ability for templates to add custom HTTP headers, which can easily be re-added if someone needs it. Thanks to asak for repeatedly reviewing this patch and helping to iron out the quirks.
