Review all automatic mails

[tymees]

The emails in the app have an inconsistent use of formal/informal language (in Dutch) between the emails, as discovered during the review of #528

All emails should be checked and changed if necessary, as it should all be informal per the UU writing styleguide.

Not sure if it makes sense to mention it here, but I happened to come across a 'short route' message, which contains at least one link that does not lead to the right information (between ** text that should be adapted):

"The FEtC-H has received your application. The automatic screening of the portal has given your application the status of short-route research. This means that we aim to send you an assessment within two working weeks.

Note: It is possible that your application may still be classified as a 'long-route research', in which case the asssessment procedure may take longer, see the regulations for information. DELETE: If the latter case, see section 2.8, p. 14 for the possible time paths.
Please be aware of these possibilities and the different time paths involved.

I just noticed the Dutch text is okay. The English version should include the text: "Houdt hier a.u.b. rekening mee."
