Cat-Printer 0.5.0

[NaitLee]

Brand new version that worth updating!

• Better experience printing, physically. E.g. quicker paper feeding, less noise (at least after printing)
• Control of thermal "strength", on both front & back end. (or the so-called "energy", "darkness")
• Drag & drop image file to Web UI. Along with some other tweaks
• Small fixes, as usual

Cheers~

Edit: 0.5.1 have important fixes. Please always use newest version!

Technical thoughts:

One thing I can't hold to say is, maybe some of those printer commands are mis-understood, for a long time.

While I'm making this new version I did more test, and found that, for example:

• It's not image_mode or text_mode. It's just applying the value after "set_energy".
  Edit: corrected this concept
• With above, the reason of "energy" not working is using the so-called image_mode or simply didn't apply it.
• I admit some points were taken from rbaron/catprinter. Actually it also helped everyone a lot.
  I see there have feed_paper and set_paper, but they are actually set_speed and feed_paper, respectively.
  and set_speed is, the lower value, the quicker feed speed.
• But who knows what's up with update_device, get_device_info, get_device_state, whatever...
  I omitted these in earlier versions but nothing bad happened...

All of these were corrected (programming-ly) and made use in newer version, 0.5

Also let me make a brave assumption: The printer firmware is used all around, but the printer vendors don't know these well either.
Many (proprietary) mobile applications were made, but none of them thought about these concepts.
(You can use their software to see what they are doing. But I know you don't want and will not use them. Me too.)
(Emm, if you once did it, still remember damned typos & confusing pinyin variable names in their code? Give them some color to see see.)
