The license.txt file has been replaced with LICENSE for quite a while
now. INAL but it didn't seem accurate to say "hey, checkout license.txt
although there's no such file". Apart from this, there were
inconsistencies in the headers altogether...this change brings
consistency.
User.language should be given higher priority in terms of
authenticated user since they chose it. Even higher than the
browser they're using...even if the system locales aren't set
properly and browser isn't configured properly
Order of priority for setting language:
1. Form Dict => _lang
2. Cookie => preferred_language
3. Request Header => Accept-Language
4. User document => language
5. System Settings => language
Cookie is placed at #2 since the language picker in the navbar depends
on it. And the Accept-Language header sends values based on the client's locales.

Form Dict _lang now accepts language codes too. Previously, language
names were used...for whatever reason.
* Remove six for PY2 compatability since our dependencies are not, PY2
is legacy.
* Removed usages of utils from future/past libraries since they are
deprecated. This includes 'from __future__ ...' and 'from past...'
statements.
* Removed compatibility imports for PY2, switched from six imports to
standard library imports.
* Removed utils code blocks that handle operations depending on PY2/3
versions.
* Removed 'from __future__ ...' lines from templates/code generators
* Used PY3 syntaxes in place of PY2 compatible blocks. eg: metaclass
Python 3 interprets string literals as Unicode strings, and therefore \s and \g are treated as escaped Unicode characters.
Fix: Declare RegEx pattern as a raw string instead by prepending r
- remove several unnecessary comprehensions from functions that accept a generator.
- Using `[x for x in iter]` causes a list to be built first then passed to the outer function.
- `any` and `all` can take generator instead. This makes memory usage O(1) and actually makes these functions short-circuiting. E.g. if the first condition fails then `all` will immediately return false instead of evaluating all the entries.
- `sum`, `min`, `max` => memory usage become O(1)
- `list`, `set`, `.join()` => roughly halves memory usage, as list is not required to be built.
- lastly, it's two fewer characters to read/think about.
Unlike the get_untranslated function, in which the file is opened and
written with the `write()` function, here the `csv.writer()` is used,
causing errors when writing encoded strings. Therefore we remove the
encoding step (The csv writer will take care of it) and we also not open
the file with binary mode.
