Messages: Reset button should be smaller as it's not that important

[slaFFik]

It's not a too often used button in a composed screen. Send (submit etc) are a main point of action for this form, so it should be big, while Reset is a complementary, so it should be styles in smaller font-size, and perhaps to the right of the text area (see attached).

Suggesting that we could also make the Reset button look like a link, the same as how @hnla has styled the other secondary buttons which are placed right after the primary button.

Yep agree, will deal with. We have a handy .text-button class that we can use.
