Accept uppercase file endings !?

[mariosgit]

Would be convenient to accept uppercase files...

My first try:

$ ./kram/kram info -i model/HONEYWELLJETWAVE_METAL.PNG.DDS
[E] Kram info only supports png, ktx, ktx2, dds inputs
Kram.cpp(1913): error:  kramAppInfo()
kram 1.0
Usage: kram info
         -i/nput <.png | .ktx | .ktx2 | .dds>
         [-o/utput info.txt]
         [-v/erbose]

Laaaaater then renamed it:

$ ./kram/kram info -i model/HONEYWELLJETWAVE_METAL.PNG.dds
file: model/HONEYWELLJETWAVE_METAL.PNG.dds
size: 0
sizm: 0.000 KB
type: 2D
dims: 4096x4096
dimm: 22.370 MP

Tested on Windows.
