PNG plugin problem

hello !
actually working on SR 1.6 and i think problem is solved (PNG I/O error)
i'm adding some debug/minor stuff, especially for rebusfarm workflow, binding the SR render button to any key, etc..
then i'll publish a new build.

Thank you Trevics, i really appreciate.

i worked very hard this week, and i'm very close to publish the 1.6.1 update.
it's a bit short, as i'm off for 4 days and will not be able to deal with eventual issues on this new build.
I prefer report to next week to be there when you test it.

I've all checked twice, but i need to verify some stuff again, especially with the PNG bug.
it's pretty hard technically and each and every case have to be tested. I really don't want to see this bug anymore

short list of what i've made since 1.5.1 :
- better management of "from scene" color mapping
- Solved bug on gamma and post (were inverted..sic)
- PNG library I/O error (and others) when using the vray frame buffer. Solved.
- Better compatibility with RebusFarm (SR can be now manipulated by farminizer)
- SR now reopens at its last position
- Hide IM and LC passes were inverted. Solved (sic again)
- Better mangement of Vray 3.0 goodies options (no more annyonning messages)
- Now there's a warning when NOT using SR render Button
- Now SR Render button is a keyboard mappable macroscript (SR_Render)
- NEW automatic Update alert system on startup

i really wanted to publish it today, but it needs a bit more of polishing.
Next week(early), i promise !!!

well i can try to add it on monday
