Modifications for SMTP in OpenSimulator. Email size limit was fixed (was out of step with documentation at 1024, so boosted to 4096). Added configuration item for maximum email size. Redundant sleep inside email module was fixed (LSL Api was already sleeping). Added sleep time configuration item for snooze between email sending for LSL Api. Added two new configuration items (email_max_size and email_pause_time) into the example OpenSim.ini, plus fixed a spelling error (llimits) and odd tabbing.
