square brackets in URL encode improperly on save and load

[ScottDillman]

This causes a url with [] to be encoded and saved and then re-encoded on load so that the URL becomes invalid and you get a failed download.

so [test] becomes %5Btest%5D which becomes %255Btest%255D

My current workaround is to use change line 252 in CurlDownload.cpp to use url.url.toString() instead of url.url.toEncoded()

I didn't have time to research if this is the correct fix or not, but for now everything is working as needed.

You are right, since the loading code doesn't urldecode the persisted URL.
