Browse Source 
* Add offset-reading capability for networked CUtlVector instances

* Use strncmp instead of strstr

* Use strcmp instead of strncmp

Co-authored-by: Asher Baker <asherkin@limetech.io>

* Move CSendPropExtra_UtlVector offset to gamedata

* Update name of offset + add gamedata entry

* tiny nits
