Standardize references to FreeSWITCH®

FreeSWITCH® should be referred to using the trademark symbol and with SWITCH in all caps.

Not:

• freeswitch
• FreeSwitch
• etc

I was going to ask about this actually. FreeSWITCH is now a registered trademark. I wonder if changing it to FreeSWITCH® would make more sense.
