Some WebAdmin tabs are broken

[NiLSPACE]

After 864e351 some webadmin tabs are broken. The commit made URLs partially lower-case while the Javascript/HTML is still using PascalCase.

I see 3 ways to fix this. We could:

• Change everything back to PascalCase / the original URLs
• Make everything snake-case. This would also require us to look into all the html and javascript code.
• Change Cuberite itself to make the URLs case-insensitive.

I personally prefer the first one. URLs now have mixed casings in it because the name of the plugin itself is also used in the URL.

Thanks for the bug report. I wasn't aware some URLs were hardcoded.

I used the same URL format as the Gallery plugin, since @madmaxoft made that change (cuberite/gallery@146f8e3) and also introduced cWebAdmin:AddWebTab in the past.
