Buildscript Updates

[ThePansmith]

Various updates and fixes to the buildscripts

• Serverpacks should be placed under the server files section (see this) instead of as an additional file under the main section.
• Have the manifest version use the tag's version (yeah I have a bad habit of forgetting to update it, sue me ), could probably just have the mainifest version be dev then replace it at build.
• Fix buildscripts so it no longer requires a file in the mod folder to build (or maybe just pretend its a feature and have it be a link to breakdown of the various optional compats idk).

Turns out that there is currently no way to have the CF API mark child files as server files, a support ticket to CF has been made regarding that.

Will reopen this if confirmed possible
