Update Dutch.xml

[robni7]

Recently splurged on the Pro version, which gave me the opportunity to have another look at the translations. Most of it is grammatical or rewording to make it sound more natural and native. Also some new tags have been translated. Things of note:

• I also added a HTML link in to the SMC reset page, but I cannot test if this automatically works (and decide if this link is desirable)
• I assumed is a Windows-only tag (whereas is Mac-only). Cheers!
