Updating from v1 to v2

There are some big changes in Laraberg v2.

• Content is now stored in a column of the model's table
• WordPress packages are available in Javascript, this means we can use a lot of the functionality, like hooks, that's already available in Gutenberg.
• @van-ons/block-editor is used to render the editor, this makes it a lot easier to keep up with the latest Gutenberg versions.
• Server side rendered blocks are now supported

Unfortunately this means that updating to v2 is not a straight-forward as we would like it to be.

• Gutenbergable is no longer used, instead use RendersContent.
• Rendered content is no longer stored in a table, so to migrate to v2 you have to move all content from the raw_content column in the lb_contents table to a column on your model's table.
• Laraberg.registerBlock was renamed to Laraberg.registerBlockType
• Laraberg.registerCategory was removed, you can use the wordpress exports to register categories.
• The configurable sidebar was removed.
• Laravel File Manager is no longer supported.
• This can be solved by implementing your own mediaUpload function and passing it as an editor setting.
