[WIP] Github Gist backend

[joostdevries]

Do not merge

Some initial work on using the Github API for this

• Implement Github Oauth using Torii
• Persist session in cookie
• Fetch gist
• Clean up Github code
• Write serializer/adapter for gist <---> file
• UI tweaks

New pointers

• Block files whose content > 1 MB (will require additional API logic + it's insane to fiddle files that large)

Use ic.ajax instead here

@alexspeller cleaned up the code.

This is looking great, do you want me to merge now or wait for the other checklist items?

[joostdevries]

I'd rather have to complete flow working first. I might run into stuff forcing me to refactor.

[alexspeller]

Use arrows instead of self = this

[joostdevries]

@alexspeller maybe we should setup Travis for this?

[joostdevries]

@alexspeller pull && http://localhost:4200/f2c90713bdfdf54a262b

[joostdevries]

The demo app is not rendering yet (don't know why) and module resolving is not working atm.

[joostdevries]

@alexspeller I've created a gists branch. Maybe it's better to merge my work into that so we can both work on it?

[joostdevries]

@alexspeller two questions:

• It looks like the resolver is not always finding the right files. http://localhost:4200/202e3ab3483386daacd2 works but http://localhost:4200/f2c90713bdfdf54a262b doesn't.
• Should we support css with this?
