This object cares for the vim langmap option and basically reverses
the mappings. This was the only solution to get UltiSnips to work
nicely with langmap; other stuff I tried was using inoremap movement
commands and caching and restoring the langmap option.
Note that this will not work if the langmap overwrites a character
completely, for example if 'j' is remapped, but nothing is mapped
back to 'j', then moving one line down is no longer possible and
UltiSnips will fail.
