Compare files and folders using external tool in fman
This is improved fork from https://github.com/rjwojcicki/SimpleCompare
Compare by content
Select file or folder in one pane and run "Compare files" to compare it with another one having the same name in the other pane. Select two files or folders in one pane and run "Compare by content" from the Command Palette.
Save to compare
Select one file or folder and run "Save to compare" from the Command Palette. Select another file or folder and run "Compare with saved" from the Command Palette.
External tools
When used first time it asks for a comparison tool. Any tool with command line interface which accepts two files or folders can be used. Example of comparison tools: KDiff3, WinMerge, Beyond Compare, or other (see this wiki article for more comparison tools).
Installation
Use fman's built-in command for installing plugins.
