More customisability.

I’m looking at creating a PR to make customising the view classes more easy. For my personal requirements I’m going to start out by just adding:

@implementation TITokenFieldView
- (Class)tokenFieldClass;
{
  return [TITokenField class];
}
@end

@implementation TITokenField
- (Class)tokenClass;
{
  return [TIToken class];
}
@end

However, this might not what you want for a PR, as it would always require a user to override both classes to customise the TIToken class. Other options are to:

• Pass a dictionary of class mappings to TITokenFieldView that gets passed along to the TITokenField instance.
• Add properties to the TITokenFieldView and TITokenField classes that specify the classes to use.
• Add delegate methods that return either classes or, (mainly) in the case of TIToken return an instance, akin to -[UITableViewDataSource tableView:cellForRowAtIndexPath:].

If you can let me know if and how you would want this to be, then I will submit a PR for that.

I've always liked the class approach, feel free to submit a pull request along these lines :)
