[Libreoffice] Renamed Linux dev packages

Hi,

we decided to use dev build for the official 3.5 beta builds but there
was missing desktop integration on Linux.

It was not easy to add it if the package name include dash '-'. In
addition, there were inconsistencies because most package names were
"libo-dev" but the ure package was "lodev". Finally, it was installed
into "/opt/lo-dev'.

I solved it by renaming everything to "lodev".

I hope that it will not break anything.


Best Regards,
Petr
