Closed Feature: Ability to exclude Fields [61]

There is an option to exclude tables while generating classes.
It would be great if you add another option to exclude some Fields also.
For example all of our tables have CreateTime, UpdateTime, etc. and they're defined in a base class.
So they should not be generated again in POCO classes.
As a workaround I did it at line #1275 of EF.Reverse.POCO.Core.ttinclude :

```
var col = CreateColumn(rdr, rxClean, table, useCamelCase);
if(col != null && col.Name != "CreateTime" && col.Name != "UpdateTime")
table.Columns.Add(col);
```

But it would be nice if you define it as Regular Expression like table filters.
