Attack/Defend-CTF Hybrid Prefab v1.3

* Fixed being able to capture points without the flag
* Fixed control point prop skins being set incorrectly

* fixed the timed-capture control points B and C being capturable without the flag (thanks TAVRAX for spotting this one)

* fixed timed-capture logic letting BLU capture the first point without the flag (thanks to Moonrat for spotting this one)

* fixed the logic sometimes giving the victory to the wrong team (thanks abp)

Everyone who downloaded 1.0 should redownload this and re-implement it in their maps.
