Button style changes cascaded to participatory texts, but broke

[basicavisual]

In order to comply with the design, the styles of the buttons where changed to be more rounded, and a larger size of text, however this was cascaded to other parts of the application as it is natural. Check the button for participatory texts:

It can be viewed by hovering over any element of the text. Fix it so that it:

1. does not break
2. uses an accent color of the cominutas branding

Use the same ultramarine color as indicated in #16
