Feature request: Gbrowse blame

[alextrastero]

First of all: bow. Great project!

Secondly, I'm not sure if someone already asked for this/duplicate dunno.
I use :Gbrowse quite often. I was wondering if there was a flag to Gbrowse directly on blame view, it would be so useful to open current line in github's blame page, ie;
https://github.com/tpope/vim-fugitive/blame/master/plugin/fugitive.vim#L47

[tpope]
