Ensures labels stay center when going to landscape
parsePanelConfigurationFileAtPath: method is private, moved away from public header
First go at getting rid of legacy object model: Label.
ORLabel is now directly part of the returned object model (this required for now ORWidget to inherit Component and some specific checks for new class that'll eventually go away) and used by rendering.
Font and color not yet supported.
iOS console does not update label values anymore for now.
Changed update mechanism to request panel definition through new client API in // with current XML download.
This means label update works when requesting an update, but not when rendering base on local cache.
Got rid of legacy Label and LabelParser
Got rid of older comments
Added font and textColor on ORLabel.
Had to move utility UIColor+ORAdditions category to client library (eventually, might make sense to have a ORCommons library for those helpers).
Tests for new textColor and font properties on ORLabel, also enforced default values in accordance with OR specifications.
Need -all_load flag for console to use category in client library
