Change "Sync Readers" to something like "Sync Aliens"

[roblingle]

copied from issue #6 on original repo.

The original intent of "Sync Readers" was to run telnet commands onto Alien Readers like the ALR-9650 to set their tagstream, name, etc. Because we now support LLRP, the nature of the button has really changed.

Here's what should be addressed:

• [ ] Sync Readers should be renamed
• [ ] The function should also check if LLRP is available
• [ ] If LLRP is available, LLRP service on the reader should be enabled

[roblingle]

Perhaps we can just do the first issue and assume the user will configure LLRP on their own?
