[🇮🇹] Italian language support

[TheMiguelBi]

I've created Italian language support for the web interface.
I think I did not understand how to update the program with the new language.
I added the string to webfile.h:
(But it is not enough).

   if (! SPIFFS.exists (String (F ("/ web / lang / en.lang.gz"))) || force) progmemToSpiffs (itlang, sizeof (itlang), String (F ("/ web / lang / en .lang.gz ")));

it.lang.gz

Thank you for your contribution, I edited your comment for better code formatting and I'll let @spacehuhn answer to this part.

Is your knowledge of github good enough so you can submit a pull request with the two updated files (it.lang and it.lang.gz) or do you prefer to leave this task to the maintainers of this project ?

Submitting a pull request will make you appear in the contributors list so proper credit can be given.

Just add the it.lang file to the web interface folder.I will do the rest and it will included in the next release :)

Okay thank you!
I have combined something, I think.
#788 and #789

Grazie mille :-)

We'll only merge the #788 for the meantime, I'm doing Travis CI tests and it'll eventually get processed automatically.

Please don't close the pull request with the .gz file yet as I have no idea when Travis CI will be able to handle that ^^

Perfect thanks!
Now I can have the web interface in Italian!

(I'm noticing any missing capital letters... I will fix the it.lang file soon.
Furthermore, the fifth "information" page has not yet been translated.).
