Support COMMENT for tasks

[rfc2822]

We could support COMMENT with the Comment field for TasksOrg-compatible tasks:

ical4android/opentasks-contract/src/main/java/org/dmfs/tasks/contract/TaskContract.java

Lines 1543 to 1565 in 93262f5

	interface Comment extends PropertyColumns
	{
	/**
	* The mime-type of this property.
	*/
	String CONTENT_ITEM_TYPE = ContentResolver.CURSOR_ITEM_BASE_TYPE + "/comment";
	/**
	* Comment text.
	* <p>
	* Value: String
	* </p>
	*/
	String COMMENT = DATA0;
	/**
	* Language code of the comment as defined in <a href="https://tools.ietf.org/html/rfc5646">RFC5646</a> or <code>null</code>.
	* <p>
	* Value: String
	* </p>
	*/
	String LANGUAGE = DATA1;
	}

• Add a comment field to Task.
• Task should be able to read the COMMENT property into the comment field
• Task should be able to generate the COMMENT property from the comment field
• DmfsTask: generate COMMENT data row (probably with language null) from Task.comment field
• DmfsTask: process COMMENT data row and fill Task.comment field from it

I hope this is even supported by tasks.org… @sunkup interested in giving it a try?

Tasks.org doesn't try to sync comments yet, but I'd like to

But we can already create the data row, right?

Sure, I wonder which servers support the COMMENT field already though? Seems like nextcloud (tasks) does not ?

When more clients support it, I guess other clients have a better chance of adopting it. As far as I know, jtx Board also supports it.
