Add a var to disable reloading the map config file on plugin load

[EvenNine]

I have found that when SoapDM is on a servers that executes another config using its map config (IE like the RGL plugins ). When the plugin reloads the cfg after round end it will cause issues with plugins such as logs.tf. In my testing i have found that it can cause the logs.tf plugin to readd the last round to a log. I have found that by disabling ServerCommand("exec %s", map); on line 513 it fixes this issue. I feel it would be beneficial to have a way to bypass this in the config.
