Show the last failed script filename when migration failed

[rdagumampan]

When migration failed due to maybe erroneous script files, yuniql must show the file name where the issue is present. Right now, it only shows the error message like the case below.

Closed. This enhancement will be part of v1.0 release.
Errors will be displayed with better color coding and shows the last failed script file.
