Bump source install to version 2.15.2
Use checksum in remote_file.
Use source install not package install on non-debian platforms.
Use file_cache_path rather than /tmp for source file storage.

/tmp may get cleaned on reboot causing unnecessary source package
donwloads.  Further many distributions are now mounting /tmp as a
tmpfs, making it ill-suited for large files.
More fixes for refactoring blunders.
Update README with new attributes.

The install_method and checksum attributes can now be used to specify
the install method("source" or "package") and the checksum of the R
source package, respectively.
Add Kitchenfile.

Currently, the package LWRP failes two of the foodcritic rules.  This
Kitchenfile ignores those tests to allow the convergence tests to
proceed until the foodcritic issues are fixed.
Merge pull request #4 from cla-rce/fix-permissions

Security: fixed world-writable Rprofile.site
consistent naming
Change cookbook name to 'r'.

This commits standardizes the naming within the cookbook to use a
lowercase 'r'.  Using 'r' rather than 'r-project' provides more
sensible resource and attribute names.  Using a lowercase 'r' ensures
that resource names have more Ruby-esque names (r_package as opposed
to R_package).

The cookbook is still uploaded to the community site as 'r-project'
since the 'R' name is already taken.
