I added a new theme

Hi, I'm new to pelican. But I spent last few weeks on it, tailoring the built-in theme 'notmyidea' to my needs.

I modified the css and template files to make it have a simpler and nicer look. And I also replaced the default social media icons with some new ones created by TheG-Force.

I attached some screen shots. Wish u would like it!
