The "fully customizable" release 🎨

v6.2.0

• Add parameters for the last two cmds without parameters (those of the update :))
• Added a kdialog trigger if a list or count cmd has an error
• Added an option to retry a list or count cmd if it has an error (disabled by default)
• Now list and count are refreshed at the end of an update
• Fix typo: 'Install all update' -> 'Install all updates' by @weelink
