New feature: update exts list versions to latest

[victormachadoperez]

Solves issue #4

Implemented new feature: update the versions of extensions in exts_list to their latest available versions.

Currently available for RPackages and PythonPackages. Implementation for Bioconductor and Perl packages is pending.

The feature iterates over all extensions in exts_list, retrieving the latest available version from CRAN or PyPi databases. It backs up the original easyconfig file and writes a new one with the updated exts_list.

Create a list including R base extensions and exclude them from update steps

 'base',
 'compiler',
 'datasets',
 'graphics',
 'grDevices',
 'grid',
 'methods',
 'parallel',
 'splines',
 'stats',
 'stats4',
 'tcltk',
 'tools',
 'utils',

For packages with missing checksum from database, add/use a function that pull the sources, calculate the checksum and return it.

@dagonzalezfo already implemented in latests commits.

Use this option to define exts_defaultclass for PythonBundles: Taken from PythonBundle EasyBlock
If ec.easyblock=PythonBundle,
elf.cfg['exts_defaultclass'] = 'PythonPackage'

[dagonzalezfo]

This is to use the same mechanism that PythonBundle EasyBlocks use to define exts_defaultclass value

[dagonzalezfo]

We need to test it for Python Bundles, but it seems that it should work as it is.

[dagonzalezfo]

Move it to a single file, proposed name exts_tools.py at tools path.
