adding a :java header argument to plantuml

* lisp/ob-plantuml.el (org-babel-execute:plantuml): Adding a :java
  header argument to plantuml.
org-export: Move translate-alist into communication channel

* contrib/lisp/org-export.el (org-export-get-environment): Move
  translate-alist in communication channel.  Refactor code.
(org-export-transcoder): Retrieve transcoder from communication
channel instead of global variable.
org-export: Fix macro expansion when back-end protects dollar signs

* contrib/lisp/org-export.el (org-export-get-inbuffer-options): Return
  an "eval" macro as a regular secondary string instead of a plain
  string.
(org-export-expand-macro): Replace arguments before exporting
them (and possibly protecting dollar signs).  Refactor code.
* testing/lisp/test-org-export.el: Add tests.
org-e-ascii: Ensure consistent cross-referencing between elements and links

* contrib/lisp/org-e-ascii.el (org-e-ascii--has-caption-or-name-p):
  New function.
(org-e-ascii--build-caption, org-e-ascii-link): Use new function.

This patch ensures only elements with a name or a caption are counted
in when a fuzzy link pointing to an element is resolved.
org-element: Fix ill-defined keywords parsing

* contrib/lisp/org-element.el (org-element-comment-parser):
  Ill-defined keywords (without the colons) are treated as comments.
(org-element-comment-interpreter): Apply changes to lexer.

use only relative paths for better compatibility with mixed Cygwin/NTEmacs installations

* UTILITIES/org-fixup.el(org-make-org-install): Use relative filenames
  throughout, and query Emacs for directory names where a full path is
  required.  This avoids Cygwin/POSIX paths being misinterpreted by a
  stock NTEmacs.  Use the same regex as (org-reload) for enumerating
  the files to byte-compile.

* default.mk: Factor out standard load-path for Emacs started in lisp/
  into BATCHL and use this in defaults.  Make all paths to be
  interpreted by Emacs relative so Cygwin and NTEmacs can coexist.

* lisp/ob.el (org-babel-capitalize-examplize-region-markers): Controls
  the capitalization of begin and end example blocks.
  (org-babel-examplize-region): Optionally capitalize example block
  delimiters.

  elements with a caption only.
(org-export-collect-tables, org-export-collect-figures,
org-export-collect-listings): Update docstring.
* contrib/lisp/org-e-ascii.el (org-e-ascii--has-caption-p): Renamed
  from `org-e-ascii--has-caption-or-name-p'.
(org-e-ascii-link): Use previous function.
(org-e-ascii--build-caption, org-e-ascii--list-listings,
org-e-ascii--list-tables): Do not use #+NAME keyword as a fallback caption.
org-e-ascii: Small refactoring
