The functions are wrappers around http and https and set the
x-xsrf-token header based on the value of the Xsrf-token cookie in the
session file.
Currently, the cookie name and header name are hard coded. I may look to
specify those in an argument at some point although for now it's
probably fine.
Cat is now a function rather than an alias. It will tie in with grc if
possible and add syntax highlighting to the file
if not, will fall back do using bat
