[Ovmsdev] OTA download incremental progress no longer happens

[Craig Leres]

When doing an OTA download the download progress used to incrementally
display, e.g. it would start with:

    Processing… (do not interrupt, may take some minutes)

and then slowly spit out a bunch of lines like this:

    Downloading... (100029 bytes so far)

And then finish with a form offering to reboot or whatever. This has
been broken for a few versions now. Basically when you start the OTA
download you get the initial dialog and then nothing happens until the
download completes and then you see the rest of the output at once.

I normally use firefox but the behavior is the same with chorme.
