WARNING: Please turn off lolisafe before upgrading, then run "node database/migration.js" once after upgrading. Ignore all errors/warnings about duplicate column name. Afterwards make sure your config.js follows the new format in config.sample.js (specifically fileLength and generateThumbnails options).
* generateImageThumbnails and generateVideoThumbnails options in config.js is now renamed to an object named generateThumbnails, with image and video as its properties.
* fileLength option is now an object with min, max, default and userChangeable as its properties.
* User may now change their preferred file length (following the previous option, of course).
* Updated a bunch of responses messages. Mainly appending a dot to the messages.
* New APIs:
/fileLength/config to get an object of the current fileLength config (exactly what is in the config.js file).
/fileLength/change to change user's preferred file length.
* And maybe some others ...?
* Adds 'enabled' column into 'users' table with database/migration.js file.
* Ignore errors when adding new columns in database/migration.js. There's a better method by checking whether the columns already exist before adding them, but this will do for now.
* Properly merged changes from master.
* database/migration.js will now exit after migartion.
* Replaced all instances of createTableIfNotExists() into a combination of hasTable() and createTable() in db.js.
* It will now properly create "editedAt" and "zipGeneratedAt" columns into "albums" table, which will then be used for the "Download Album" feature. Previously, due to the lack of those columns, people could not download albums. Existing installation will have to do some manual patches, which I will describe further in the commit's comments.
* Thumbnail-less files will properly show the extensions in albums. Previously it would have two dots.
* Switched ESLint + Aqua to Standard. I'm a big fan of Standard. Updated yarn.lock file too.
* Lots of refactors to follow the rules of Standard.
* Fixed issue with uploading as a not logged in user.
