Fix styling issues

[kbsriram]

With the new onboarding flow changes, the existing UI styles have been affected and need to be updated.

• All text is centered
• Buttons look too big
• Hard to see the separators between threads/messages

But I'm waiting for #8 to be merged, as there are new style changes incoming.

Hey @kbsriram, according to the UI for attachments, the position/ordering of buttons is slightly changing as well, therefore I scheduled the CSS changes together with the details about attachment icon and input, being both effected by each other. It's in the next CL.

These are fixed:

• All text is centered
• Buttons look too big

As for the separators between messages/threads, I'll fix them according to https://github.com/e2email-org/e2email/blob/05a24965c7bd97c75d5eada1857f222acf546ff7/screenshots/basic.png.
