removing hardwired paths from CMD

[gfursin]

At the moment I hardwired path in scenario CMD such as '$#local_path#$/openscience/data/ba4.../topology/deploy.prototxt'

Instead, we should use '$#ck_local_path#$/$#SCENARIO_KEY_TOPOLOGY#$'

Android app should substitute $#ck_local_path#$ with {sdcard}/openscience
and then check all files to find a key SCENARIO_KEY_TOPOLOGY (not done yet - I have to add it to meta) and substitute $#SCENARIO_KEY_TOPOLOGY#$ with data/ba4.../topology...

Then we will not have any hardwired path in scenarios any more.
It's not urgent and we need to do it at the same time on Android side and CK side ...
