For the Doom IWADs the provided font looks almost identical to the characters used on the title patches. So, for any level name that got replaced in some language, it will now check if the retrieved name comes from the default table, and if not, ignore the title patch and print the name with the specified font.
This also required removing the 'en' label from the default table, because with this present, the text would always be picked from 'en' instead of 'default'. Since 'en' and 'default' had the same contents, in any English locale the 'default' table was never hit, so this won't make any difference for the texts being chosen.
Last but not least, wminfo has been made a local variable in G_DoCompleted. There were two places where this was accessed from outside the summary screen or its setup code, and both were incorrect.
This is dpne as a two-stage approach. TXT_LOGTEXTxxx will always take precedence over the log lumps, and TXT_ILOGxxx will only replace the original IWAD content.
This is so that PWADs replacing these lumps don't get overridden by the default texts.
It now reads everything into a two-dimensional TMap and creates a list of mappings that apply to the current setting.
The constant need for reloading was the main blocker in redesigning how Dehacked strings get inserted. Currently they override everything, but IWAD-based Dehacked text shouldn't block PWAD overrides from PWADs' LANGUAGE lumps and instead be treated as coming from an [en default] block.
This also renames the main block from [enu default] to [en default], because it should be treated as the English default for all English locales and not just make it fall through to the base default as it did before.
Two files were split:
g_level.h contained both the game data definitions and some prototypes belonging to the game logic. These were split up.
decallib.cpp contained both the data and the animation thinkers. The thinkers are now in their own file.
