* PartFinder now finds part for the special case of no PART{} structure.

* Closed some left-over open StreamReaders.
* Fixed bug in part finder where the same part was added multiple times. Caused by the mod developer having multiple instances of the same part (not good)
* Fixed null modtitle and null modparts exceptions.

* Also asks user to input a mod name to avoid having empty mod names alltogether.
* Fixed infinite loop issue with PartFinder special case.
* Converts underscores to periods in part names as required by tech tree

* Fixed bug where parts whose name line had tabs instead of spaces wouldn't be found
