Tyson Andre cdcec69536 Support the pylint output format
This is a compact output format that is easy to write scripts that parse.
(And errors fit on a single line)

- E.g. jenkins violation plugin works reliably with pylint.

The multi-line details are deliberately omitted.
An application can output 'console' to stdout and to
a pylint file at the same time.

Files with the extension .pylint will use this format.

Document the emacs and pylint output formats in `psalm --help`

An optional followup task would be to create unique issue codes,
I don't have any use cases for that.

Usage:
psalm [options] [file...]
Options:
-h, --help
Display this help message
-v, --version
Display the Psalm version
-i, --init [source_dir=src] [--level=3]
Create a psalm config file in the current directory that points to [source_dir]
at the required level, from 1, most strict, to 5, most permissive
--debug
Debug information
-c, --config=psalm.xml
Path to a psalm.xml configuration file. Run psalm --init to create one.
-m, --monochrome
Enable monochrome output
-r, --root
If running Psalm globally you'll need to specify a project root. Defaults to cwd
--show-info[=BOOLEAN]
Show non-exception parser findings
--diff
Runs Psalm in diff mode, only checking files that have changed (and their dependents)
--self-check
Psalm checks itself
--output-format=console
Changes the output format. Possible values: console, emacs, json, pylint, xml
--find-dead-code
Look for dead code
--find-references-to=[class|method]
Searches the codebase for references to the given fully-qualified class or method,
where method is in the format class::methodName
--threads=INT
If greater than one, Psalm will run analysis on multiple threads, speeding things up.
--report=PATH
The path where to output report file. The output format is base on the file extension.
(Currently supported format: ".json", ".xml", ".txt")
--clear-cache
Clears all cache files that Psalm uses
--no-cache
