Use v:roundrect for actionItems in Outlook.

See #16 for relevant conversation. I made as minor changes as possible.

See screenshots in Chrome + Outlook 2013 below. Let me know if you have any concerns.

Hi @charlie-s,
Thanks so much for this contribution! 😄

Any chance you would be willing to apply this fix to all four mailgen themes?

These are:

• default
• neopolitan
• salted
• cerberus

Thanks again! 👍

[charlie-s]

Definitely. Will implement and update the PR. I need this asap, and I imagine anyone else using the built-in themes does as well whether they know it or not :)

See latest commit for Cerberus. BTW – is this Cerberus pulled from https://github.com/TedGoas/Cerberus?

Neopolitan already uses v:roundrect to add round borders to its actionItems.

Salted's code is a little different and so I've left it alone. It uses large borders to achieve a button look (instead of padding) and they render fine in Outlook, albeit without rounded corners. Since they're legible, and there are many other issues for Salted in Outlook, it's probably best handled separately if someone uses it. Would you agree?

Hi @charlie-s,
Sounds great! 💯 Well done mate.

Agree on what you said. Yes, it's the same Cerberus theme you linked.

Merged and published in 2.0.7.
