As discovered by WouterSmits, campaigns with periods in their filenames caused issues with FSO's campaign handling. Specifically, in The Babylon Project, the EA-Minbari war v1.0.fc2 campaign would not save progress because FSO expected EA-Minbari war v1.fc2 in certain places. This is because the `_splitpath()` function attempted to remove an extension from a filename that already had it removed. For most campaigns this did not matter, but WouterSmits found a campaign where it did.
To solve this, there is now a new `util::get_file_part()` function to remove the path without removing the extension. This replaces `_splitpath()` for campaign files, as well as the similar `clean_filename()` and `GetFilePart()` functions in other places. All code paths were inspected for any chance of inadvertent extension adding, and Assertions were added to verify future code. The only potential problem area was `player:loadCampaignSavefile()` which now pre-removes the campaign extension if needed.
