'RimPy.sh: No such file or directory' if PWD is not the RimPy directory

[Little-119]

Tiny inconvenience:
Executing RimPy.sh when the current directory isn't the RimPy directory returns
./RimPy_Linux/RimPy.sh: line 2: ./RimPy: No such file or directory
as its looking for the RimPy binary relative to $PWD

This can be fixed by changing the line
LD_PRELOAD="libpcre.so.3:$LD_PRELOAD" ./RimPy
to
LD_PRELOAD="libpcre.so.3:$LD_PRELOAD" $(dirname $0)/RimPy
making the bash script successfully executable from an arbitrary directory
