Add HTTP server

[Feuerswut]

Chrome removed ftp:// protocol from their codebase, hence ftp is not only deprecated, but unabailable for most users.

I suggest using codebase from a simple http server, or writing one as a priority and replacing ftp protocol.

I think webdav server is good too.

I suggest add sftp or ftps server. Since using ftp in a shared network is not safe, even more dangerous in open WiFi.

I think webdav server is good too.

Webdav is based on http. Would be nice to have but fewer file manage program support it, and less flexible than ftp.

for daily use, it's better to have a client, so the best choice is webdav and ftp, sftp.

for temp use. it's better to not require a client, so http and wendav will be the choice.

so webdav is the best for both situation. i think webdav is the next generation rule line. there are lots of file manager support webdav : mix explorer on android, dolphin in linux ....

i want to replace mix with materialFiles. but the only reason let me keep mix is the webdav.
