Cleaning: Add exclusion rule for other auto-generated files

Currently CodeMaid excludes 2 types of files from being processed:

• T4 generated files
• Files where the name matches a regex pattern

For other auto generated files, it would be useful if there is an option to exclude files which contain the auto-generated header. An example is when creating a webreference or servicereference to an asmx or wcf webservice a file reference.cs is created.

The header has the following syntax:

//--------------------------------------------------------------------
// <auto-generated>
// Description
// </auto-generated>
//--------------------------------------------------------------------

WSDL reference files are another great example. These files can be huge, example at codecadwallader/codemaid: Issue #135

We'll now check and disable cleanup whenever the phrase <auto-generated is detected in a document.
