Fix params from improper encoding

[Peripheral1994]

CC @ladanazita @hankim813

This rectifies the issue where Nanigans was receiving parameters incorrectly due to QS calling encodeURIComponent on them. We now use our own function to encode.

This relies on a report from Ladan, as I've been unable to find supporting documentation myself, so having her review would be appreciated. :)

Old behavior example: &sku%5B0%5D
New and desired behavior: &sku[0]
