Charles LeDoux 4d1167ffd7 Parse cli and stowrc files separately
Why:

* We want to selectively apply expansion to:
    * Only options from stowrc files.
    * Only options that take a path.
* This requires ability to:
    * Differentiate cli options from stowrc options
    * Distinguish between individual stowrc options.

This change addresses the need by:

* Options from ARGV and stowrc files are separately parsed, resulting in
  two options hashes.
    * Creating an option hash from stowrc files allows modification of
      specific arguments without having to rely on something like regex
      parsing of the options.

* get_config_file_options modified to return options hash.
    * Uses the same parse_options function that parses ARGV

* Add Hash:Merge to dependencies in order to merge the two option
  hashes.

* process_options() merges the two option hashes.
    * Get option hash for ARGV
    * Get option hash from get_config_file_options().
    * Merge the two hashes with Hash::Merge.
    * Sanitation and checks are ran on the merged options.

* The options -S, -D, and -R are ignored in stowrc files.
    * Due to the way argument parsing happens, the effect of these
      actions is not carried from stowrc into parsing of cli options.
    * It doesn't seem to make sense to put these options in stowrc
      anyway.

ERROR: bin/stow contains 'use lib' line which could interfere
with CPAN-style installation via Module::Build. To avoid this,
you should run ./configure with parameters which result in
--with-pmdir's value being in Perl's built-in @INC, and then run
'make' (NOT 'make install') to regenerate bin/stow, e.g.
eval `perl -V:siteprefix`
./configure --prefix=$siteprefix && make
or
./configure --with-pmdir=`PERL5LIB= perl -le 'print $INC[0]'` && make
Then re-run this script.
Note that these parameters are chosen purely to regenerate
bin/stow without a 'use lib' line, so don't run 'make install'
while Stow is configured in this way unless you really want an
installation using these parameters.
