move save and auth buttons into editor header
indicate current user in auth dropdown
s/change book/change repository/
change hover behavior to make modules looks both draggable and clickable
add tooltip to further indicate simultaneos drag/click behavior

This is problematic because it 1) will interfere with showing full title
and 2) it also appears in picker, not just TOC.
instead of entire item feeling draggable, make it appear based on a hook at left

includes several styling changes to make the drag hook/handle look nicer
with the other icons/text
Tom hooked me up with an isPicker variable: sweet (like :cake:)
Tom made me an ancestorSelected variable so we can have context-based messaging. Thanks :cake:
prevent drag handle from showing up in picker books

further color changes

I changed the green/teal/orange slightly from the mock-ups, since they
were looking off on some monitors. Hopefully this is better. This also
has further color changes, mostly related to tree highlighting.
remove problematic CSS in response to phil's concerns

- Will just use browser-specific grabby hands; other browsers too-bad
so-sad, I guess.
- Changed from attribute selectors to class ones, so that the dragging
override class selector has same specificity and therefore won't require
"!important"s on its "cursor" declarations.
move content-pannel height declaration into gh-book.less
use blue for 'save' button that doesn't clash as much

Also change the module editor color because the previous orange just
clashes with everything i tried
