NewFileFilter and button color

[Guiorgy]

the new File Filter didn't behave as intended, also forgot to set the buttons text color (only did it to the drawables)

if (!files.remove(dirFile)) {
     files.add(dirFile);
}

remove returns true if item was removed and false if not, in other words, if a File was selected twice it has been deselected, hence we remove it from the list.

PS. just check the FileUtils, and FileChooser changes ignore everything else XD

also noticed that, when you go to a new directory (or go back) it doesn't reset your scroll position.

@hedzr , so I cannot make a pull request because they "are entirely different commit histories."

anyways check my 'empty' branch hotfixes commit. what I did was:

• fixed the NewFileFilter.
• fixed the button text colors.
• fixed deleting files in select multiple mode. (!most important)
• made the list scroll to top when changing directories.

my fault to reformatted codes in one of commit. i'm checking and working there.
