		Recursively search for files containing text.

		Mandatory parameters:
		  --search <text>, -s <text>          Text to find

		Optional parameters:
		  --folder <x>, -f <x>                Folder to search (default '.')
		  --pattern <x, ...>, -p <x, ...>     File patterns to match eg '*.txt,*.docx' (default '*')
		  --open-with <x>, -w <x>             Open files with this program instead of Notepad

		  --inside-zips, -z                   Always search inside zip files. Implies -p *.zip
		  --one-thread, -o                    Don't search files in parallel
		  --case-sensitive, -c                Text is matched in a case-sensitive way
		  --hide-errors, -h                   Hide errors from the output list

		Examples. Search current folder for txt and Word files containing "hello world":
		  Searcher.exe --folder . --pattern *.txt,*.docx --search "hello world"

		Search just zip files for anything containing 'hello':
		  Searcher.exe -f . -p *.zip -s hello

		Search txt files (including those in zips) for anything containing "hello":
		  Searcher.exe -z -f . -p *.txt -s hello
		Or..
		  Searcher.exe -f . -p *.txt,*.zip -s hello

		Search txt files (excluding those in zips) for anything containing "hello":
		  Searcher.exe -f . -p *.txt -s hello
