- updated to libreoffice-3.5.5.2 (3.5.2-rc2)
- basis subdirectory does not longer exists on the installed system
- remove unused ooo_piece_version, ooo_build_version, and ooo_sourcedirname
macros

- generate the whole spec file from a template and a data file
- do not recommend help packages and dictionaries; they provide support
for the given locale itself; the extra recommends annoys users
when updating on Live-CD (bnc#551003)
- use Requires(pre) instead of PreReq on never distributions
- spec file clean up
