examples: Cleaned up C examples.

This commit cleans up multiple items with the UPM C example source.

    * Switch from usleep and sleep to upm_delay* methods
    * Include a mraa_init and check return value prior to using sensor
    * All example mains now return
    * Added include for mraa.h and upm_utilites.h to all examples
    * Reformatted/removed tabs
    * Updated author line for the examples I wrote
