Changelog:

0.5.1:
- (improved) Until now, when opening the popup, if the page failed to load (it did not even return a status code), the message "loading, or no data available for this page, try reload the tab" was displayed. Now, when this situation occurs, a message "error page, no data available for this page" is displayed to differentiate both cases.
- (fixed) The copy headings option in the Headings tab did not generate the text string properly when there was an empty heading (i.e.: <h3></h3>) on the page.
- (fixed) Fixed bug that caused, in some cases, a page canonicalized to another page using a canonical tag with a URL without a domain to be mistakenly identified as INDEXABLE when it should be classified as CANONICALISED.
- (fixed) Fixed bug in Schema tab where tags with an itemscope attribute without itemtype attribute were shown in the structured data list as "null". Now they are displayed with a more descriptive message: "(No itemtype)".
