translations extracted by pybabel

[roganw]

fabmanager babel-extract won't extract the string of __(msg).
So, I extract the translations by command:
pybabel extract -F ./babel/babel.cfg -k __ -k _ -o ./babel/messages.pot .

__ and _ are the alias of gettext and laze_gettext respectively.

LGTM. At some point we'll have to figure out how we manage translations on the frontend side.

@mistercrunch Yeah, some messages in js files need to be translated, we can refer the solutions of other application.
Such as Odoo, which extract to po by babel and load translations to frontend variable by JS request.
extract js translations in the backend

from babel.messages import extract
extract_method = 'javascript'
src_file = 'js file path'
extract_keywords = {{'_t': None, '_lt': None}}
extracted = extract.extract(extract_method, src_file, keywords=extract_keywords)

And then translate on frontend side

(It's exciting if FAB contains these function. )
