Tilde character in mod names breaks WeiDU.log

[Argent77]

WeiDU is currently ill-prepared when mods contain tilde characters (~) in their TP2 filename or mod folder name. The string is placed into the WeiDU.log as is. As a result WeiDU triggers a cryptic warning and silently removes the whole line and every line before from WeiDU.log in a subsequent install or uninstall operation.

There should be a way to add this character in a compatible way, e.g. by escaping the character or using a replacement code. Alternatively WeiDU could prevent problematic mods from being installed at all.
