Add support for btn styles on button elements

[timojarv]

Currently elements with "siimple-btn" styles have ugly default borders on them. This pull request removes borders from buttons so that the "siimple-btn" styles can be used with regular elements.

Hello @timojarv !

First, thanks for your PR! The changes on scss/btn/_btn.scss are perfect and necessary, but there are some problems on the others files:

• The file yarn.lock is necessary?
• All the modifications on the dist/ folder are irrelevant, because they will be overwritten when I publish the new version. The only important changes are in the scss/ folder.

Please, can you do a new PR with only the changes on scss/btn/_btn.scss?

Hi, Yeah, sorry about the /dist modifications, your build script seemed to duplicate the .min files. The `yarn.lock` file, while not strictly necessary, is usually included in the repo since it will benefit the people who are using yarn instead of npm for deps managements. ti 28. helmikuuta 2017 klo 10.48 Josemi Juanes <notifications@github.com> kirjoitti:

Ok, I will remove manually the extra css files in dist. Thank you! 😄
