Updating zc-hacks.php to zc-cache-lock-type.php.

Incorporate the details I discussed here.

I suggest we create a separate KB Article called "What is cache locking?" that includes those extra details. We can then trim this KB Article down a bit and move the explanations to the other KB Article.

Copy that. I started writing another article about this here: #36

I was just reviewing this. The above ↑ is correct.

<?php
add_filter('zencache\\share::cache_lock_lock_type', function(){
    return 'sem';
});

After Restructure Is Complete

• The preferred filter name will be: zencache_cache_lock_type
  The old filter name will continue to work however.

<?php
add_filter('zencache_cache_lock_type', function($type = 'flock'){
    return 'sem';
});
