Better Screenshot taking action

[Shajirr]

Current action:

• has no control over the screenshot name or where its saved. Has no way to get this data to use in the macro later.
• displays screenshot-taking system UI, which can interfere with and break the script if it need to use UI interactions

A better alternative:

• being able to specify save path + file name of the screenshot
• does not display any interface while taking the screenshot, so will not interfere with any scripts using UI interaction

An example of this already implemented can be seen in an Automate app
