Add login page

[agnesjang98]

Allow a user to login and authenticate with their GitHub username and password. The login page can just point to a pre-specified repository's dashboard (the repository name is hard coded in the main.dart file).

The login page should be similar in concept to: https://github.com/GitHawkApp/GitHawk
To summarize the goal, what GitHawk's login pages does is send the user to the mobile browser which directs them to the GitHub login page and will ask them to log in through there. Alternatively, users can also enter their GitHub Auth token as a form of authentication as well.

For dx-mobile the acceptance criteria is as follows:

• Create a page that has a login button/some object that directs the user to a mobile browser which allows them to log in and authenticate through GitHub's mobile website
• The page should also give the user an option to log in with their GitHub token
• Upon completion of logging in, the user should be taken to the page that displays a list of the user's repositories.

Please feel free to comment if the AC is unclear!

Hello! I'd like to work on this!

[agnesjang98]

Hi @rjheim! Thanks for commenting and sorry for the late reply. To give you some background, we'd like to implement a login page similar to https://github.com/GitHawkApp/GitHawk (which you can download from the app store if you have an iPhone). I will update the issue description for it to be more clear.

For now, do you have any clarifying questions?

Alright I'm working on it!
