Removed update functionality && Rewrote/simplified file handling && Expanded README

With this commit I will change the scope of this project. The new goal for this project is to rewrite the file handling of the original update script in C#. Because of this a lot changed with this commit.
I removed all update functionality from the code. I completely rewrote the file handling with help of the FileInfo class. I also added a couple of things to the Roadmap. While doing that I also added sources that I frequently use.

+## Roadmap/ToDo
 
 - Figure out how to do options/arguments
-- Backup important files
-- Figure out how to make a single executable
+- Backup all necessary files
+- Shrink size of the executable
+- Potentially speed up file handling
+- Color output according to state (success = green, failure = red, info = yellow)
+- Backup pacman database
+- Compress all files to single archive
