autodetect RS2014 installation folder from steam vdf

this addresses #5

I'd rather it would get back to previous approach in case of failure

[xenein]

I could change the python-script to return the old default path in case of error.

but: is still relevant with your second comment? if awk is used instead, awk could handle that case, too.

[xdexer]

It still should go back if it cannot find the file or awk fails for whatever reason

Nice script, but in .command script it uses python3 explicitely, which can make it not usable for some users of old MacOS. It is a good idea to do it like that, but what do you think to stick to bash only? To make it more versatile?
awk '/221680/ {found=1} {a[i++]=$0} END {if(found) for(j=i-1;j>=0;j--) print a[j]}' "~/Library/Application Support/Steam/steamapps/libraryfolders.vdf" | awk '/path/ {print; exit}'

Explanation:

/221680/ {found=1}: When a line contains "221680", it sets the found flag to 1.
{a[i++]=$0}: This stores each line in an array a.
END {if(found) for(j=i-1;j>=0;j--) print a[j]}: After processing all lines, if found is set, it prints the lines in reverse order.
awk '/path/ {print; exit}': This looks for the first occurrence of "path" in the output and prints it.

I'm not firm in awk, but it sounds quite right.

alternatively: there is from __future__ import print_function and this is about the only thing not python2-compatible.

I am fine with both approaches and don't want to push the awk, because it is harder to read.
