Rename/Remove files that differ only by case

There are multiple files in this repository which have file paths that differ only in letter case including the ones for the following AppImages:
- LMMS
- OpenBlok
- BotFramekwork-Emulator
- ShareXin

These files make it very difficult to contribute on file systems which do not support case-sensitive file name (ex. OS X). If this was not intentional, could you please merge these files? If it was intentional, can you please use an alternative naming scheme such as adding a suffix?
