Fixed compilation error in basalt_logger where it whined about or'ing together two enum values for the log level.

Browse Source 
Fixed a compilation error where the log level mask was being shadowed by log level index in basalt_log and basalt_write.
Fixed a bug where logger_add_stream was checking the lower 48-bits of the FILE* rather than the upper 16 were zero.
Fixed a bug where logger_add_stream did not mark a stream as allocated in its flags.
Fixed a bug where logger_remove_stream did not check if a stream was allocated.
Addressed warnings of potential saftey issues when logging the prefixes as if they were format strings by having them be format-specified. I suspect this is marginally slower and realistically had no security risk in the first place but was fixed anyway.
