Link to an image or video in another file that has an `\x` on title from another file

Issue report at: github.com/ourbigbook/ourbigbook/issues/198 Suppose you had:

programming-language.ciro

= Programming language

\Image[https://raw.githubusercontent.com/cirosantilli/media/master/python-logo.jpg]
{title=The \x[python-programming-language] logo}

== Python
{c}
{disambiguate=programming-language}

logos-i-like.ciro

= Logos I like

\x[image-the-python-logo]

Now, when rendering \x[image-the-python-logo], we would need to fetch two IDs:

image-the-python-logo for the The and logo part
python-programming-language itself, to know that \x[python-programming-language] should render as Python

But after group all SQL queries together was done, there was no way to know that rendering image-the-python-logo would imply also fetching python-programming-language.

This was solved by adding a new database entry type, REFS_TABLE_X_TITLE_TITLE to the existing References table, which tracks dependencies between IDs.

After this was setup, we can now know that image-the-python-logo depends on image-the-python-logo, and then fetch both of them together in a single JOIN.
