ob-lilypond: Code cleanup

* lisp/ob-lilypond.el (org-babel-lilypond-OSX-ly-path,
  org-babel-lilypond-OSX-pdf-path, org-babel-lilypond-OSX-midi-path,
  org-babel-lilypond-nix-ly-path, org-babel-lilypond-nix-pdf-path,

  org-babel-lilypond-determine-ly-path,
  org-babel-lilypond-determine-pdf-path,
  org-babel-lilypond-determine-midi-path): Remove.
  (org-babel-lilypond-ly-command, org-babel-lilypond-midi-command,
  org-babel-lilypond-pdf-command): Replacement for removed variables
  and functions.  Adapt all calls to the removed functions to use
  these variables instead.
  (org-babel-lilypond-commands): New defcustom for setting up
  the *-command variables.  Keep different defaults for different
  systems as the original code did to avoid tripping up unsuspecting
  users.
  (org-babel-lilypond-execute-tangled-ly,
  org-babel-lilypond-check-for-compile-error): Revert conditions to
  avoid superfluous forms.  Remove unused return values.
* testing/lisp/test-ob-lilypond.el: Do test for new variables and
  replace removed function calls with the appropriate variable
  content.  Exercise the new defcustom thoroughly.
Revert "org-clean-before-export matches non-special columns spuriously"

This reverts commit 79873390edd26a44cefc2050c7af470a7ed8fd07.
The fix was wrong and gave rise to a different problem  - see

   http://thread.gmane.org/gmane.emacs.orgmode/89945

Revert it for now, since there is a workaround for the original
problem and plan on a correct fix in the near future.

inline and standard code blocks.

of switches and header arguments as in "src_sh[]{echo foo;}".  Also
permit spaces before them.

inline source code.

function for testing inline source code handling.  Also add three new
failing tests exhibiting unexpected results with ":results code"
switches.

inline source blocks with empty header arguments.

Until now pieces of inline source code were handled as standard code
blocks during export.  These changes enable them to be exported.
