[Patch] Update opening_hours.js

[simon04]

opening_hours.js has gotten many improvements since its last release on 2017-02-18: ​https://github.com/opening-hours/opening_hours.js/compare/v3.5.0...master
In particular a rather heavy external library could be removed via ​https://github.com/opening-hours/opening_hours.js/pull/250
When also excluding the country holiday data via ​https://github.com/opening-hours/opening_hours.js/pull/314, one can build a opening_hours+deps.min.js bundle with only 170KB whereas data/validator/opening_hours.js now has 316KB.

There are the few necessary modifications within JOSM: attachment:18577.patch​​

Two JOSM tests fail with the new version, however:

java.lang.AssertionError: 
Expected :isEmpty()
Actual   :<[service_times - Mo-Fr 00:00-00:30,04:00-00:30; Sa,Su,PH 00:00-24:00 <--- (This rule overwrites parts of the previous rule. This happens because normal rules apply to the whole day and overwrite any definition made by previous rules. You can make this rule an additional rule by using a "," instead of the normal ";" to separate the rules. Note that the overwriting can also be desirable in which case you can ignore this warning.) => Mo-Fr 00:00-00:30,04:00-00:30; Sa,Su,PH 00:00-24:00]>
