unity-tweak-tool does not honor Hidden=true parameter in icon index.theme files.

[PJSingh5000]

If Hidden=true in an index.theme file, the theme is listed and selectable in the Unity Tweak user interface, but the theme should not be visible.

TEST #1:

1. Open the Hicolor icon theme index.theme file (/usr/share/icons/hicolor/index.theme).
2. Notice that index.theme file has "Hidden=true" on the fourth line.
3. Launch Unity Tweak, and navigate to the Icons tab.
4. Notice that the Hicolor icon theme is visible and selectable.

TEST #2:

1. Edit an icon theme file under /usr/share/icons/.
2. Enter Hidden=true in the [Icon Theme] section.
3. Launch Unity Tweak, and navigate to the Icons tab.
3. Notice that the theme is still visible and selectable.

BACKGROUND:

According to "Icon Theme Specification" at Freedesktop.org...

"Hidden - Whether to hide the theme in a theme selection user interface. This is used for things such as fallback-themes that are not supposed to be visible to the user."

Status changed to 'Confirmed' because the bug affects multiple users.

This is indeed the case. Thats why we see Dmz-white and Dmz-black mouse cursors in Unity Tweak.
