Ctrl+number cannot select channel groups on Linux/Windows

[MKimiSH]

I believe the cause is the !(modifiers & SYSTEM_COMMAND_MOD) in the following line:

tev/src/ImageViewer.cpp

Line 686 in 1335273

if (key >= GLFW_KEY_0 && key <= GLFW_KEY_9 && !(modifiers & SYSTEM_COMMAND_MOD)) {

. On Windows and Linux, this is the same as Ctrl, so it blocked the Ctrl+number key combination. This seems related with introducing Ctrl/Cmd+0 and Ctrl/Cmd+9 for setting image transforms.

I think the new Ctrl+0/9 behavior is more useful than selecting the 9th or 10th channel group. Meanwhile, we can perhaps keep Ctrl+[1-8]? It introduces a bit of inconsistency though.

Oops, good catch! Thanks & sorry for the accidental breakage. Just pushed a fix that makes Ctrl+1-8 work (I agree 9 and 0 aren't necessary here).
