r15610 fix this.

Testing:

1. make sure your cluster.php is changed according to default_cluster.php.template in r15610.
2. goto myamiweb/processing/emanJobGen.php?expId=8525
3. select a stack with more than 1000 particles and a model
4. use default parameter for iteration 1 and the cluster that the change has been made.
5. check the jobfile created. The part says #outfullpath should be correct. If it is a remote cluster like garibaldi, the final rsync that copies the results back should also have the right path.

Found that this a general problem and that formatEndPath function is defined at multiple places.

The new inc/cluster.inc did not use formatEndPath and causes path problem if not DEFAULT_APPION_PATH not end with '/'.

Move the function into particledata.inc since all of them call it except the ones derived from default_cluster.php.template.

These are committed as r15882
