Plyara version changes

[Taskr]

Newer versions of plyara have different output and semantics - will need to adjust YaraGuardian accordingly.

Since plyara version 2, metadata field in parsed rules changed from a dict to a list of dicts. You can see 'complaints' about this in this issue: plyara/plyara#52

It would be easier if you force or recommend to use some specific version. Last plyara version that returns a dict is 1.4.1.

This would be helpful too with the Django version, as some views name were refactored:

YaraGuardian/YaraGuardian/urls.py

Line 45 in c09d8f0

auth_views.password_reset_confirm, {'template_name': 'prelogin/ResetPassword.html'},

and

YaraGuardian/YaraGuardian/urls.py

Line 49 in c09d8f0

auth_views.password_reset_complete, {'template_name': 'prelogin/ResetPasswordSuccess.html'},

django version 2.0 is the last version that uses the same view names as you.
