Support running via "idat"

[srmish-vdoo]

When running sark scripts via idat, sark causes IDA to abort because of qt imports
(I'm guessing the qt DLL can't be loaded into a console process? Maybe it's looking for user32 functions?)

Specifically, IDA aborts the script's execution with the error:
DLL load failed: The specified procedure could not be found

Workaround
Comment out any code that uses Sark's ui module:
__init__.py Lines 36, 48
function.py Line 9 (and subsequent uses of updates_ui)
line.py Line 8 (and subsequent uses of updates_ui)

Steps to reproduce (Windows)
Run from command prompt:
"C:\Program Files\IDA 7.2\idat.exe" -S"somesarkscript.py" someidb.idb
