More file attributes (hidden, read-only, ...)

[Maingron]

Add more file attributes to files and folders that allow them to be hidden, for example.

Think they should be stored like in the following example, using a-z, A-Z and 0-9 - only one per attribute, giving a total amount of 62 possibilities.

Example list of attributes (non-final draft):

• a: hidden
• b: read-only (user initiated)
• c: read-only (system initiated, can't be changed by user)
• d: read-only / file opened right now (temporary flag)
• e: temporary file (can be used to fetch and clean temporary files)
• 0: sensitive system files (system variable, for example)
• 1: sensitive user files (user variable, for example)
• 2: user file
• 3: program file
• A: Color dot 1
• B: Color dot 2
• C: Color dot 3
• D: Color dot 4
• E: Color dot 5
• F: Color dot 6

Example:

A=ab1 = hidden, read-only, sensitive user file

For now, ABCDEF0a are implemented as suggested
