More useful commands to document for testing tips section

Copied from messages on Discord:

• for multiple statements in a script command use the compilestring("")() function
• reload
• uiscript_reset basically reload but for the ui vm useful for making UI stuff
• the last tip I can think of is make global test functions to call with script, script_client or script_ui
• script StimPlayer(GetPlayerArray()[0], -1.0) for infinite stim without hud effects
• script GetPlayerArray()[0].kv.airAcceleration = 9000 9k air accel
• script_ui seterrorhandler(void function() {}) deletes the ui error thingy (useful for fucked up persistence when you don't want to reset it)
• DispatchSpawn( CreateAtlas( team, position, angles ) ) creates a weaponless titan, team = 1 will make it hostile
