More Substitutes like %P

[nikhilhassija]

Since, working directory is only set once, and in my case it's the directory ~/CP. And, after that there are directories for each online judge, further each such directory has a sub directory for contests held over on an online judge. Although, there is an option to manually select working directory while parsing the contest, but that deviates from the automation Hightail tries to provide, by requiring to manually locate directory.

So, I propose following substitutes to help with automating this part.
%S - For online judge, like "codeforces", "codechef", "atcoder", etc.
%C - For contest code, like '818' (CF Round), 'JUNE17' (CodeChef long challenge). (These codes are present in URLs for contest, and thus easily parsable.
