Add the filter aliases for phpcs options

[marcelsud]

Currently PHPCS haves the following options:

--report=<report> 
--report-file=<reportFile> 
--report-<report>=<reportFile>
--report-width=<reportWidth> 
--generator=<generator> 
--tab-width=<tabWidth>
--severity=<severity> 
--error-severity=<severity> 
--warning-severity=<severity>
--runtime-set key value 
--config-set key value 
--config-delete key
--config-show
--standard=<standard> 
--sniffs=<sniffs> 
--encoding=<encoding>
--extensions=<extensions> 
--ignore=<patterns>

Maybe we can add some alias to them, or just bridges in order to call that options during the sniff.

For the related --standard=<standard> option, see https://github.com/devdrops/diffcs/issues/1 (status: To Do) and #6.

I suggest that the --report-width=<reportWidth> flag would be set as default inside the app, since it's useful to be executed every time.

Suggestion: --report-width=auto, which will display the entire output without breaking lines.

Some options don't make sense with the diffcs scope, then I will add these ones:

--report=<report> 
--tab-width=<tabWidth>
--severity=<severity> 
--error-severity=<severity> 
--warning-severity=<severity>
--sniffs=<sniffs> 
--encoding=<encoding>
--ignore=<patterns>

The option --report-width=<reportWidth> will be added as defalt and will be possible to be overwritten when sent by the user
