Title: TTree draw, context and rootpy browse enhancements

This brings a little thread safety to the contexts which
are useful for weboot-like environments.

TTree draw now won't ever pollute gDirectory and has been
simplified to remove obsolete code.

rootpy browse now doesn't have duplicated keys when browsing a file.
