#19 World name save extensions (lower case)

[Tom Bashford]

More a query than a bug:

I notice that the file extension inside the worlds folder is lower case .wrz whereas the default ones are .WRZ. Wondering still if case sensitivity is picking up the wrong file name and path extensions.

Case differences appear in world name extension, world convertor, zipping/unzipping, and potentially for switch names. Also within Scenario's menus when displaying switch names and music names in lists.
The only issue here is perhaps consistency (although if GFA Basic is case senstive then care must be taken).
