Multinetwork WiFi, TCP support, OTA support

Note: If you are currently using older firmware (2.x or lower) you will need to load v3.x firmware using a USB connection. We have created a Windows GUI to ease this process. Please see Updating Firmware from GUI for a step by step process. Once you've updated to v3.x firmware, you will be able to load future firmware using any method (SD, WiFi, OTA, USB, or GUI).

Changes in this release:

• Enable OTA Pull: Allows users to update firmware by checking the SparkFun server. Docs

• (Feature #354) Add device configuration over Bluetooth. Docs
• (Bug #353) Reinitialize SD in case of disconnect
• (Bug #368) Fix the list of common coordinates on AP page. Docs
• (Feature #323) Add file manager to AP config page. Files can be downloaded, uploaded, and deleted from SD. Docs
