This update is needed to get Languagetool working with LO-3.5

- maintenance update (bnc#769793, bnc#769593)
- fix build with LO-3.5:
* basis directory does not longer exist
* use libreoffice instead of libreoffice-ure in BuildRequires
- generate the whole spec file from a template and a data file
- update license to follow spdx.org standard
- spec file clean up
- updated to version 1.4:
* add support for Khmer
* update rules and dictionaries for almost all languages
* pressing [CTRL+Ret] will check the current text
* fix pre-selection of user's language
* use localized screen messages and buttons
- updated License tag to mention also 3rd party stuff
- removed obsolete Jaminid and jdic sources
- called unopkg-sync-bundled in post install scripts; added
libreoffice-3.4.2.4 into PreReq (bnc#712358)
- renamed lo-LanguageTool* helper scripts to lo-languagetool to better match
the package name
- disabled help content that was not displayed; unopkg complained about it
in the %%posttrans script
- fixed handling of the architecture dependant symlinks (bnc#677354,
MaintenanceTracker-39716)
