Version Control With Subversion Source

Set svn:eol-style to native on all text files which did not already have it.

Re-commit the initial modifications made to the build files in the Italian
build sandbox directory.

* src/it/lab/Makefile.base-rules
* src/it/lab/Makefile.base-vars

Copy, unchanged, relevant build system files into src/it/lab/.

* src/it/lab/Makefile.base-rules
* src/it/lab/Makefile.base-vars

Delete src/it/lab/*.orig, because storing copies of original files which are
already under version control in the same repository is a little pointless.

* src/it/lab/Makefile.base-rules.orig
* src/it/lab/Makefile.base-vars.orig

Delete files which were added, instead of being copied with history,
because this made imporant differences much less obvious.
(These will be recreated correctly in a moment.)

* src/it/lab/Makefile.base-rules
* src/it/lab/Makefile.base-vars
