[FEATURE] Chitra through application manager

[mngshm]

This app is supposed to be open through an application manager example rofi, dmenu, gnome application manager etc. In linux, application managers find and start the app from /usr/share/applications . Chitra needs to have its startup file with the name chitra.desktop here in this directory.

The structure should be somewhat like this:

[Desktop Entry]
Name=Android File Transfer (MTP)
Comment=Transfer files from/to MTP devices
Exec=android-file-transfer
Icon=android-file-transfer
StartupNotify=false
Terminal=false
Type=Application
Categories=Utility;System;FileTools;Filesystem;Qt;

for this to work, the app binary should be installed on the path.
