Fixed errors on npm install, and customized profile CSS

[TechGeek01]

When I initially cloned this repo, npm install gave me some errors when it built. I was able to fix them with npm audit fix, which updated a bunch of the npm dependencies. The original commit from my repo that fixes this issue is b2906d0.

Additionally, for my own blog, I felt the profile picture, especially if this is meant also as a sort of portfolio as well as a blog, is kind of small, both on the sidebar, and on the card. This has been changed, to make them more adequately fill the space, and make better use of the profile picture itself, since it's kind of hard to see a clear photo at 110x110px on the card. This is still hardcoded, but this addresses some complaints found in #401 and #417

Running npm audit found some vulnerabilities again, so I've fixed this with e415e6c.
