enhancement: add holidays (PH) to the opening hours instead of reporting an error

[Gorgonz <gorgonz@…>]

What steps will reproduce the problem?

1. create some opening hours manually and add "; PH Su off"
2. activate Plugin opening hours
3. select: edit (this) opening hours
4. plugin reports a lexical error

What is the expected result?

well, you told, that it would not work, but i would argue for an error free reaction, so that users won't think, that this syntax is wrong. Best of course would be, to implement PH ;-)

What happens instead?

You get the lexical error

Please provide any additional information below. Attach a screenshot if possible.
