Rename components to use CamelCase convention

UpperCamelCase, actually.
(Closes #201)

I could only find time to go through half of the files changed. I have some feedback for now, I will get to the rest later, maybe after the requested changes are made.

• test-info, withIntl, utils - These files do not necessarily export components. So these can remain the way they are. withIntl is a HoC definition and usually starts with lowercase.
• AsnSelector, UrlChart - This is not a big deal, but it should be consistent. In some places it is ASNSelector in others you used AsnSelector. Since they are acronyms, I prefer ASNSelector and URLChart.
  box.js - This doesn't export a Box component, instead exports a couple of variants. So maybe rename it to boxes.js (yes, lowercase).
  flag - This hasn't been renamed yet, but you already import from ../Flag in one of the files. Same with header and footer.

I understand this is a lot of tedious work and it is much appreciated. Thank you ❤️

I am guessing renaming TestInfo back to test-info should avoid the merge conflict now showing up here after I merged a PR recently.

Well, there is a problem in my git configuration - don't merge this yet

When you think it is ready for review just use the "re-request" button(last step) to notify me.

I discovered the problem. I thought it was my Git configuration, but turns out that I was editing on a case-insensitive file system. Sorry about the mess - everything is properly renamed.

Thanks @lucaspontoexe for the PR. I added a few fixes because I felt some files need not be renamed, and a few imports needed to use new filenames. This is ready for merge.
