replace encode calls with encodeURIComponent #4
Description
While dockerizing nodeStorage, I ran into encode function undefined error. I did notice that there are several instances of encode function sprinkled around in both javascript and OPML files so there error was probably caused by trigger some area not typically covered.
Since encode function maps directly to encodeURIComponent, I think they can be replaced with direct calls except in one javascript file where encode is defined differently.
This is an enhancement only and not required for dockerizing.
