I added to the main repository the changes that romeo did with some improvements.


New version 1.2

- Added all new agents;
- Added thirdperson preview when choosing agent;
- Added convar "sm_csgoagents_previewduration" to control preview duration (Disable: 0);
- Added convar "sm_csgoagents_hideplayers" ("Hide players when thirdperson view active. Disable: 0; Enemies: 1; All: 2). Default: 1.
- Added optimizations for the hideplayers feature.
