reservedKeyword parser is broken.

[goatherd]

Could not parse namespace or class names.

Does fail to abstract as the sniff is registered to match finally keyword only. (may use different issue to track those)

[goatherd]

May not be able to detect this directly using php 5.5 or newer as finally is a keyword itself.
Sniff behaviour certainly depends on Tokenizer implementation as the context defines the token class.

May need to verify that it is used in context.
