Sync config folder to common folder

The development of this plugin was motivated by the following two reasons:

• The config folder for Obsidian must start with a dot (.);
• Some synchronization tools used do not support syncing folders that start with a dot (.).

Therefore, the plugin was developed to synchronize the contents of the config folder to a common folder with the command Sync, and it also supports restoring the config folder from the common folder with the command Restore.

The settings for the common folder support both relative and absolute paths, with relative paths based on the root folder of the current Vault.

开发本插件的原因是基于以下两点：

• obsidian 的配置路径必须以 . 开头；
• 使用的部分同步工具不支持同步以 . 开头的目录；

所以开发该插件将配置目录的内容同步到普通目录之中（Sync 命令），也支持将配置目录复原到配置目录之中（Restore 命令）。

设置的普通目录支持相对路径和绝对路径，相对路径基于当前 Vault 的根目录。
