remove the "old" i18n support,
vdr-1.6 is available since 2008-03-23 and should updated on 99% of user systems

the atched diff will remove all i18n crap,
also it will remove support for all older versions befor vdr-1.5.7

to make it more clear for users they will try to compile the cleaned plugin version on older vdr version,
you can add the following code snipe in display.c
maybe you have also to #define the APIVERSION in the Makefile to export it on compile

<snipp>
#if defined(APIVERSNUM) && APIVERSNUM < 10507
#error "VDR-1.5.7 API version or greater is required!"
#endif
</snapp>
