Dependency checking and local versions of mods

[Xymanek]

At the moment the sole source of the dependency checking logic is the workshop metadata, which has a shortcoming - it cannot understand that a local mod is the same one as "requested" by a workshop id, thus creating false positives.

The worst "offender" in this case is the CHL which has a lot of dev/pre-release versions, but other mods can also encounter this issue.
