Desktop: Fixes 7434: Encode file path uri in addPluginAssets

[Wartijn]

Encoded all off the special characters, except for /, of the file paths in addPluginAssets so they don't' get a special treatment (e.g. removing everything after a # when loading the stylesheet, like happened in #7434)

I'm not sure how to add tests for this, but I've tested this manually in Linux by changing the id of the current profile so it contains these characters.

I don't think this fix is right. script.src already encodes the data so if it doesn't encode it properly it's because the input is wrong. Most likely those Windows paths should be converted to forward slash beforehand

It's not just on Windows though. If I add a # to the path by changing the profile id to foo#bar nothing after the # will be read in Linux.

I've tested it some more, and it seems that only ? and # cause errors, because everything after those characters will be ignored. That seems to make sense, since you won't need to read anything after that when loading a file as stylesheet or script from a url.

Please remove

Yes I guess you're right, currently it's handling # and ? in a special way, but in this particular case it shouldn't since it's a local path

It's all good now, thanks @Wartijn!
