instancetype goodness
start of a podspec
still need to factor out the third_party bits before pushing to Specs though
keeping xcode/llvm happy
replaced CTTabContents object with a protocol and NSDocument based implementation
seems to basically work
proof of concept view controller tab contents
with lots of copy/paste...
Merge branch 'feature/remove-nsdocument-dependency' into develop
added required resources to podspec
fixed reference to Toolbar.xib
allow user to supply custom vertical offset
fixed bug where (under arc) simply dragging a single tab window via the tab would close the window
Set the new tab button to not have a border.
