Fixed EXT-6790(major) - Limit to amount of text output to script error/warning window is to limited.
Could not find history for floater_script_debug_panel.xml. Looks like current max_length="10000" was randomly picked as a reasonable value at some point of viewer-2-0 development.
Using viewer-1-23 value for max_length - "2147483647"
