Don't set the background of the app

[arthsmn]

Currently the background of the app is set, so when using a transparent background terminal the app looks odd.

@arthsmn can you post a screenshot? That would be helpful. Also if you haven't generated the theme file yet, generate it using the instructions in the theme branch of this repository.

A preview of the problem:

As you can see, first my terminal isn't setting a background color, so it is blurred. When selecting the instance, it's still blurred. But, when the app opens the background is set to black, which overwrites the blur.

Ok, A small fix has been issued now. Install the latest version first.

For background transparency:

• If you don't have the themes directory within your config folder (~/.config/invidtui for example), do invidtui ---generate first. A themes directory with a default.theme file will be generated. (~/.config/invidtui/themes/default.theme for example)
• Now, open the default.theme file, edit the Background property to bg:default within the App context. It should look like this:

...
{ 
  App: {                       
    Author: attr:bold; fg:purple
    Background: bg:default
    Border: attr:bold; fg:white
    FormButton: attr:bold; bg:blue; fg:white
...

• Save the file, and relaunch invidtui.

For theming any other properties, refer to the themes branch.
