Improve run-lines Functionality

[TheNexusAvenger]

While working with Innovation Security, we discovered a couple of things with respect to run-lines when using init-edit and init-run:

• By default, it doesn't appear to work at all since it uses Dispatcher:Run(...), which only works on the client, but is called by the server.
• run-lines does not work with client commands, like alias.
• run-lines throws an error if the input text contains a percent character anywhere.

This pull request attempts to address those problems by making run-lines run on the client instead of the server, and escape percent characters before being used with gsub.
