Merge lp:~milo/linaro-image-tools/bug1057639 into lp:linaro-image-tools/11.11

[Milo Casagrande]

Branch adds default value for bootloader option when none is passed on the command line.
Default bootloader is set to 'u_boot'. A warning will be printed on the command line when no bootloader is specified.

[Paul Sokolovsky (pfalcon)]

Good approach on issuing a warning in case explicit value is not provided (I assume we want user to know what bootloader they will use by specifying it themselves). Also assume that moving logging configuration section around was necessary.

review: Approve
