Connecting to password protected feeds

[G. M.]

Describe the bug
cannot register to RSS feed that requires user/pass credentials

To Reproduce

• hit "+" to add a feed
  a- there's not place to enter user/pass
  b- if I type "http://user:[e-mail]", which is a valid URL format, I get error "unknown host" as it seems "user:password@" is interpreted as part of the host name instead of being extracted independently.

Device (please complete the following information):

• Aggregator version: Latest in Play Store (sorry, found no way in the app the get the version...)
• Device: Doogee N10
• Android version: 8.1
