Add default startup and automatic configuration

[perinm]

Right now i run each separate command, would like to have a .sh added to startup with all the following commands:

# 1
discord --start-minimized
# 2
slack -u
# 3
telegram-desktop -startintray
# 4 - couldn't figure it out how to start this one minimized
upwork

Such commands should be automatically configured in ubuntu startup using new_system.sh, and parhaps other .sh file to just store this commands.

Right now I configured using this "startup applications" manually, would like to not be necessary to use this window for such configuration, just plain .sh
