add option "--ignoretables" to BackupCommand.php

[jenswittmann]

What does it do ?

Add the mysqldump parameter --ignore-table.

Why is it needed ?

Sometimes you don't need to backup tables like modx_context_setting or something like that. Now you can ignore this table with gitify backup --ignoretables=modx_context_setting. I use this to do a local backup and restore to the live server, but don't want the context settings for SmartRouting.

I wonder if we should name it --ignore-table for consistency with the mysqldump syntax but other than that, this is a good improvement. Thanks @jenswittmann!

@Mark-H feel free to rename it 😸
