Improved Pod Pairing error message

[marionbarker]

This change modifies what is shown to the user in the situation where there is a Bluetooth error.

This particular error has caused several people (as reported on Facebook) to discard their pod and try again without realizing that toggling Bluetooth on the phone will probably solve the issue.

Note - this is an OmniBLE specific issue. The OmniKit messages do not need modification.

Test:

• Use rPi to trigger the error (shown on left of graphic)
• Build using this modification and trigger the same error (shown on right of graphic)

Edited to show new graphic from latest commit (35d5bcb).

We should to limit the use of possibleBluetoothIssue error to only underlying commsError cases and it should be independent of whether a pod was found

Modified the code to address the issues mentioned by @ps2 and updated the graphic to go with new code.
