improve display of history items

fixes #86
github is inconsistent (surprise!) about how many history items it returns
when it's a regular load -> includes current version
when it's a change -> does not include current version
this was causing not all history items to show
skip more metadata when comparing old notebook version

we calculate a full notebook diff when forking an old
version of a notebook, and must skip both r_type and r_attributes
fixes #101
change get_github_url to get_conf_value

allow fetching arbitrary values from rcloud.conf
artifacts
new-format github gist urls

slightly more robust github url parsing (split by '/')
if rcloud.conf has github.gist.url, use new format urls
don't show history if none showing

fixes #105
latest jqtree
upgrade jquery to eliminate toggler display bug

jQuery 1.7 animation was setting overflow:hidden on elements
and not restoring, clipping the toggler control
center jqtree toggler vertically
revert jqtree.css and override ugly default properly
notebook scrolling somewhat improved
update password prompt to bootstrap 3
