Modify upload page wording to include .7z files

[notabotscott]

When uploading wordlists or rules to the dictionaries, the following text is present at the bottom of the upload page:

Files must be plain-text or Gzipped. Gzipped files must use '.gz' file extension. Tarballs are not supported.

However, it is possible to upload .7z files and have them properly processed.

Can the text be changed to include .7z as an acceptable file extension? This will prevent someone (definitely not me though) from unzipping a .7z file and rezipping it as .gz.

Sorry for the slow reply. It's rare that I get issues where someone says "Hey, this unsupported thing actually works totally fine" - it's kinda nice!

I'll get this updated.
