Model Id converter should use IDE configuration from edit modes

[x87]

Currently when running model id to name and name to id conversion tool (Ctrl+Alt+H) Sanny always uses the game directory as the input for the GetObjectID lib. As game directory is now optional #48 and IDE files could be local (see custom edit modes by OrionSR #6) the conversion tool simply doesn't work when the game directory is not set.

Need to come up with a proper way of dealing with missing game directory. As an option use IDE configuration from modes.xml

Potentially it's possible to load all model files in all modes similarly to what VC Mobile mode does (sannybuilder/data#11). But the performance of autocomplete is still poor. Editor responds too slow to typing # when there are thousands of models.

See this suggestion: #17 (comment)
