Make more precise the description of the arguments of checker in the doc.
Reformat the description of checker in the doc.
Allow easy inclusion of sample inputs in gen/GEN
Fix and streamline GEN file loading in YamlImporter and cmsMake.

Also, implement correct dependency tracking for #COPY: statements.
Use more descriptive names for variables.
Clarified that checker is executed on the workers

When the computer where the task is prepared has a different
architecture than the workers, it is possible that the resulting
checker does not run correctly on the workers. Thanks to Gabriele for
the spotting this.
Reming to compile the checker statically in the task type page
Basic implementation of Polygon format loader
Support multiple datasets (Polygon)
Fixed task parameters handling (Polygon)
Factor out the root dirs of the trees in the setup
Ability to import polygon tasks from non-installed CMS
Add documentation for Polygon
Force C/C++/PAS oom test programs to use resident memory

It seems that the compilers are smart enough not to allocate the whole
array in memory if we are just using some portion of it.
Fix array overflow, improve tests fairness
Evaluate submissions on each testcase separately
Filter elements of ES to be returned in queue_status
Sweeper optimization
Change format for queue content display

Also a few minor fixes to stress test.
