This setting allows to escape HTML in markdown rendering or not.
The goal behind it is to avoid XSS issue in shared instances.
More info:
* the setting is set to true by default
* it is set to false for anyone who already have the plugin enabled
(avoid breaking existing entries)
* improve the HTML sanitization when the setting is set to false - but don't consider it XSS proof
* mention the setting in the plugin README
All existing link will keep their permalinks.
New links will have smallhash generated with date+id.
The purpose of this is to avoid collision between links due to their creation date.
creation and update dates are now DateTime objects.
Since this update is very sensitve (changing the whole database), the datastore will be automatically backed up into the file datastore.<datetime>.php.
* search type now carried by LinkDB in order to factorize code between different search sources.
* LinkDB->filter split in 3 method: filterSearch, filterHash, filterDay (we know what type of filter is needed).
* filterHash now throw a LinkNotFoundException if it doesn't exist: internal implementation choice, still displays a 404.
* Smallhash regex has been rewritten.
* Unit tests update
* Searching '-mytag' will now exlude all shaares with 'mytag' tag.
* All tags starting with a '-' are renamed without it (through the Updater).
* Unit tests.
Minor code changes:
* LinkDB->filter() can now take no parameters (get all link depending on logged status).
* tagsStrToArray() is now static and filters blank tags.
* contains methods designed to be run once.
* is able to upgrade the datastore or the configuration.
* is based on methods names, stored in a text file with ';' separator (updates.txt).
* begins with existing function 'mergeDeprecatedConfigFile()' (options.php).
