Refactoring

Fixing "* interpred as argument prefix" syntax checker warnings, code
indents, newlines at EOFs so you can read code in shell using `cat`,
extra newlines, double quotes to single quotes where it is semantically
correct (so it will pass Robocop style checker), fixed HTTParty
dependency (it is runtime, not development one)
