Upcoming functionality in bioc_tool_init and other features:

• planemo bioconda_pull_request
• planemo bioc_tool_init --rscript (this should parse the Rscript directly and fill in inputs and outputs directly making the tool definition file, getting requirements directly)
• Improve ``bioc_conda_recipe_init` to make both Bioconductor and R recipes

This goes with the PR #492
