Add error message(s) to console output

[pmrotule]

The message logged on error was only including the error count and the file where the error occurred. Hence I modified the code to print the error message(s) on the next line. The message logged in the console now look like this:

Message:
    1 error detected in 4.elements/images.scss
        - Please check validity of the block starting from line #14
    2 errors detected in 6.templates/help-center-nav.scss
        - Please check validity of the block starting from line #46
        - Another error
Details:
    domainEmitter: [object Object]
    domain: [object Object]
    domainThrown: false

...instead of:

Message:
    1 errors detected in 4.elements/images.scss
2 errors detected in 6.templates/help-center-nav.scss
Details:
    domainEmitter: [object Object]
    domain: [object Object]
    domainThrown: false

My modifications are made in ES6.

Can we add this? This is really useful if you need both an output file and want to know what happened in the console

Is there any reason for this not being merged? This is a necessary feature!
