At the moment, the Slack integration sends a notification when:

• a project is added/deleted
• a language is added/deleted/completely translated
• translations are flushed
• strings are imported
• a comment is added on a string
• an administrator/contributor is added/removed
• a contributor joins a public project
• the string limit for the account is reached

Please provide more flexibility by enabling us to switch off some of these notifications.
Our use case is that we are mainly interested by "strings are imported" events but these notifications get lost in the flood of "a comment is added on a string" notifications.
