Remove unnecessary tags from string resources

[domdomegg]

Summary:

NB: This has potential merge conflicts with #2741, so probably best to wait until that's merged before working on this (or work on just the ones outside WelcomeActivity).

Would be ideal to remove any tags like CDATA or <u> from string resources. There are probably more but the ones I know about are the 'More information' link from WelcomeActivity, and all the links from AboutActivity. Ideally we should store just the link text in strings.xml, then use a Spannable / similar to give the links an underline, and use onClick listeners with either lambda functions or Butterknife to call Utils.handleWebUrl.

Would you like to work on the issue?

No, but this would be a perfect first issue (when #2741 merged)

I can take a look in to this when #2741 is merged

To be assigned to @ronanb80 once #2741 merged
