Subject: [PATCH] error propagation bugfix
upload_config: renamed to download_config
plot_IR_data.py: simplified plot and file naming; enabled download of temperature errors in example; added time trace plot of T(t) with error bars from some random point in image
downloadversionIRdata.py: get_temp_from_raw_by_program_V1() now reads error images for interval chunks and returns all in error_images
downloadversionIRdata.py: get_temp_from_raw_by_program() avoids crash when returning error_images in FLIR camera case (not computed for this camera)
downloadversionIRdata.py: apply_calib_on_raw() does now set error_images to 0 for each image, if no NUC happened (Infratech case), avoiding a crash in the error propagation
downloadversionIRdata.py: warning output made resilient for non-string type Exceptions
