[libvoikko] Grammar checkers, hyphenators and libreoffice-voikko

[Harri Pitkänen]

Using the latest sources for libvoikko and libreoffice-voikko you should now 
be able to use grammar checkers made for different languages in LibreOffice 
without changing the language code to "fi". Previously this only worked for 
spellers. I made the same improvement for hyphenators as well although right 
now we only have a hyphenator for Finnish.

You can also use voikkospell to list the supported capabilities for different 
languages:

$ voikkospell -L
spell:en
spell:fi
spell:mhr
spell:sma
spell:tt
hyphen:fi
grammar:fi

This listing should match the view LibreOffice has about language tools 
available through Voikko.

Note that there is one corner case issue that can show up on developer systems 
but not likely on end user systems. If you have multiple dictionary variants 
for some languages and they support different capabilities it is possible that 
LibreOffice ends up using a variant that does not have the requested 
capability. The variant is of course not selected randomly. The one that is 
selected in the preferences will be used.

In order to implement this new API some changes were made to dictionary 
loaders. There is a new class called BackendProperties that holds three 
properties. Name and path of the backend existed already before as attributes 
of the Dictionary object. The third property is a boolean property 
isAdvertised which can be used to specify if the backend should be advertised 
in the list of supported capabilities. Usually this property is false for null 
backends and true for "real" backends.
