Fixed a few issues that occurred because LinkedIn changed their HTML layout

[ykahlon]

• Fixed skills listing
• Fixed about bio (+ expand state)
• When clicking on some 'expand' buttons, you were redirected back to the feed, and then a lot of information was missing.
• Reformatted the code (with Intellij's ctrl-alt-L)

Any update for this? I found when I run the scraper I cannot get the correct user profile.
