Tabs instead of Switch in problem page

Materialized tabs added to view submissions in a categorized fashion.
My submissions | Friends' submissions | Global Submissions.

Sweet User Interface for tables

All the submission tables and the contest table now show the profile site logo instead of naively mentioning the name ;)

No separate friend request page

'Show tags' button instead of giving a Spoiler ;)

Problem page instead of displaying the problem tags directly includes a button only on-click of which the tags are displayed.

Mark contests whose reminder is already added

If you have added a reminder for a contest, then it will show a disabled button and hence save you from duplicating the reminders (Needless to say - You must have authorized StopStalk with Google)

Instead of treating a partially solved problem as solved problem, a separate submission status is specifically introduced. Note: Already retrieved submissions are not updated but all the new submissions will be marked appropriately.

Editorial Links added

Editorial Links added in the problem page. Note: This is only if the profile site actually has the editorial for that problem.
