No login link when "Links and resources" block is present

Patch for "master" branch: https://reviews.mahara.org/5972

This bug is actually present going back at least to Mahara 1.10, although it became more evident after we added the $cfg->showloginsideblock setting in Bug 1434131 for 15.04.

Prior to that, the "Login" link was displayed at the top of the screen if you're logged-out, you're not on the transient login screen, and there are no sideblocks on the page. Presumably the coder who originally wrote that, didn't realize there were situations where you could be logged out and see sideblocks without also seeing the "Login" sideblock.

In 15.04, it became easier to create this condition, by setting the $cfg->showloginsideblock to "false", which removes the Login sideblock everywhere.

I should note that the previous behavior was to display the login link *or* the login block, *not* both. I'm open to discussing a change to display both, though.

My initial feeling, however, is that it makes more sense to show only one or the other; showing both would probably confuse users.

To clarify my previous comment: The patch 5972 changes this so the login link is always showing, when you're logged out. I misread the description of this bug and thought the bug description was asking for that. But on further discussion, the bug report doesn't ask for that. So it's just a problem in the current design of the patch.

The important bit is that when you have $cfg->showloginsideblock = false; that you should

1) see a "Login" link at the top right
2) and see the "Links and resources" block
3) but no "Login" sideblock

And if you have $cfg->showloginsideblock = true, you should

1) not see a "Login" link at the top right
2) see the "Links and resources" block
3) and see the "Login" sideblock

Bug 1537912: Allow the 'login' link to show when sidebars exist

There was a setting to stop the login link (top right) from showing if
there were sidebars on logged out homepage. This became a problem if
the login box was turned off (not counted as a sidebar block for some
reason) via $cfg->showloginsideblock = false;

But the top right login link should always show when logged out
whether a sidebar is in play or not.
