Armbian ConfigNG desktop entry and icons

[Tearran]

Description

16x16

32x32-256x256 and SVG

Implementation Details

• Key changes introduced by this PR

  • Added icon files in multiple sizes (16x16, 32x32, 64x64, 128x128, 256x256) and a scalable SVG format.
  • Created a desktop launcher file configng.desktop to allow easy access from the desktop environment.

• Justification for the changes
  The inclusion of different icon sizes ensures that the application icon appears crisp and appropriately scaled across various display settings. The desktop launcher file simplifies user access to the application, improving usability and integration with desktop environments.

• Confirmation that no new external dependencies or modules have been introduced
  No new external dependencies have been added. The changes only involve adding icon files and a desktop launcher configuration.

Testing Procedure

• Test 1: Verified that the icons appear correctly in various sizes (16x16, 32x32, 64x64, 128x128, 256x256) when used in the desktop launcher and application menu.

  • Results: Icons displayed correctly in all tested sizes.

• Test 2: Tested the desktop launcher by placing it on the desktop and verifying that it launches the application as expected.

  • Results: The desktop launcher successfully starts the application.

Add script to resize, convert, and place icons in appropriate locations

• Added a script (./tools/svg-png.sh) to convert an SVG file into PNG files of sizes 32x32, 64x64, 128x128, and 256x256 pixels.
• The script places the converted PNG files in their respective size-specific folders.
• Example usage: ./tools/svg-png.sh configng-cpu will resize and convert ./share/icons/hicolor/scalable/apps/configng-cpu.svg.
• Note: Inkscape must be installed for the script to work.
