Skill icon update

[Berkmann18]

At the moment some icons are available in FontAwesome, ForkAwesome and Font MFizz, and leaving some the text there is quite offputting.
Icon list to update:

• Express
• PugJS
• ASM
• MIPS
• Processing
• Matlab
• Webpack
• GIMP
• PhotoFiltre
• Photoshop
• A. Illustrator
• Inkscape
• XML

ForkAwesome have now implemented Inkscape,
I found a webpack icon on Icomoon.

There's also DEV for the front page.

Hashnode and DEV.to are supposedly done in ForkAwesome.
Same goes for Boostrap so hopefully I wouldn't need Font MFizz anymore.

[Berkmann18]

Gimp is supposedly ready in ForkAwesome.

[Berkmann18]

Hashnode, DEV (on FA 5.4.1), Bootstrap and Gimp aren't on ForkA yet.

[Berkmann18]

C is supposedly now available in ForkA.

C, DEV, GIMP, Bootstrap and Hashnode are on ForkA (according to this) but not on the new CDN version yet (v1.1.5).
