A bunch of copyediting-grammar, spelling. (#20)

Definite improvements except:  I changed the description to
*TINU is the open tool to create bootable macOS installers.*
It ends in a '.' so it should be a sentence.  Or this would be OK:
*TINU, the open tool to create bootable macOS installers*

 # For the latest Source code check out the development branch!
 
 # Features:
 - No need for guides or instructions! Just follow the very simple on-screen indications to very easily start the bootable macOS installer creation process.
-- Fully open: You can see how this programs works and you can freely contribute to it! (See the `Repository rules` and the `Note that` sections of this page)
-- Support for multiple languages (currently just italian and english, but more will be added with future updates once the system which allows it gets improoved)

+- Support for multiple languages (currently just Italian and English, but more will be added with future updates once the system which allows it gets improved)
 - Can work with every macOS installer app that has the `createinstallmedia` executable inside its internal resources folder (including also beta and newly released installers).
 - 100% clean using the official apple's method: The bootable macOS installers created with this tool are made using the official apple's `createinstallmedia` method, just as if you created them using the command line, this ensures the best and the cleanest results avoiding all the problems that modded installers have.
-- Does not require any special preparations. Just open the program, make sure you have a big enought USB drive plugged in (see the `Requirements` section) and have a macOS installer app on your disk.

-- A copy of a macOS/Mac OS X installer app (Maveriks or newer versions are supported), it's reccommended to have the app placed into the /Applications folder or in the root of a volume connected to your computer (excepted the drive/volume you want to turn into your macOS install media).
