I tried to change messages that contained instructions for users,
while avoiding messages that are so technical that most users
wouldn't understand them even if they were in the right language.
Since the menus aren't actually assigned a parent, they would not be freed by wx. Plus, these should have initially been constructed on the stack in the first place.
Technically any time someone right-clicked the game list they would be leaking memory.
Minor other alterations that relate to above as well.
Also added the PanicAlertT version of alerts for some error messages that
use PanicAlert. We want the user to actually understand why the error
occurred.
- remove unused variables
- reduce the scope where it makes sense
- correct limits (did you know that strcat()'s last parameter does not
include the \0 that is always added?)
- set some free()'d pointers to NULL
