[Features request] Add theme background and about option to open flashlight application

Components

A simple, open source flashlight is an android flashlight(torch) application.
The application does not have theme feature where different background colors can be selected, and it lacks about option which is an important option on any application.

Proposal

Theme background feature is very important because it enables users beautify the application by selecting their favorite color.
About option is a must feature on any application. I suggest this option should be implemented because with the option, it users will be able to know the developers of open flashlight, when and where it was produced and other details about the application they are using.

Mockups / Examples

The image below shows where these options should be located.

The second image shows the setting option wher the theme feature should be located and the about option.

Benefits

The users of open flashlight will benefit much if these features would be implemented, because it users will be able to customize the application with their favorite colors and different background would be selected. And the about option will give them the knowledge about the application their using, the producers and when/where it was produced. It will be as a plus to open source.
