Most importantly, specifying a patch may optionally disallow showing the autor's name - this is for cases where a styled patch gets used for English but text-based translations of the map name should still be possible.
Exit_Normal and Exit_Secret specials imply addition conditions to make a decision about proceeding to the next map
A few scriptified actors require a bypass of these conditions in order to work properly
Now it's no longer possible to manipulate TID hash from arbitrary location
For example, this prevents linking of destroyed object into the hash
TID member is still public but writing to it is limited to a few very specific cases like serialization and player traveling between levels

* consolidated C_MidPrint and C_MidPrintBold.
* removed some unused code from the console buffer.
* handle console output of centered messages to ensure they get written to the log file and to stdout.
* replaced the non-standard bar strings with simple '-'s. These were making things needlessly complicated when redirecting console output and the new font does not have the characters anyway.
* removed some old code from a time when during console drawing new network events could come and have more text printed. This can not happen anymore with how 2D elements are being handled now so all this code was redundant.
This variable is needed long after the function which sets it up will be exited. So this either needs to be dynamically allocated or static, and in this case using a static variable is simpler. However, unlike before, it is only being accessed in the one function that needs to initialize it and pass to the summary screen and nowhere else.
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.
Having everything lumped together made this a maintenance hassle because it affected how the level has to be stored.
This hasn't been tested yet, so it may not work as intended!
currentUILevel is now primaryLevel.
For ZScript, currentVMLevel was added. This is also exported as 'level' and will change as needed.
This also means that no breaking deprecations will be needed in the future, because in order to sandbox a level only 4 variables need to be handled: level, players, playeringame and consoleplayer.
The remaining global variables are not relevant for the level state.
The static 'level' has been mostly removed from the code except some places that still need work.
I think these were the last two still missing it, all remaining uses of the global level variable are in code that doesn't get run through a level tick and are supposed to access the primary level.
The Map loader may not access any global state at all - everything it can touch must be exchangable.
Furthermore, if we want to sandbox each level, there may be no direct access to any kind of global state whatsoever from the play code.
