Ckeditor5: Review button and command names

[Reinmar]

I'd like us to take a final look at the commands and buttons exposed by this feature.

E.g. I've noticed that the table.toolbar option is set to: [ 'tableCell', 'tableRow', 'mergeCell' ].

My first thoughts were:

• tableColumn and tableRow are overly generic. Perhaps tableColumnActions? OTOH... KISS?
• mergeCell – similarly generic and not true now, because it doesn't merge anything. But we plan to make it a split button soon, so it will merge cells. Exactly – cells, not a cell. Hence, WDYT about mergeCells?

It'd be good to check other commands and buttons too. I haven't paid much attention to them earlier because we didn't know what UI we'll end up with.

Yeah - I've used simpler names as we do not have headingActions or similar things in other dropdowns.

Them mergeCells might be not-so-distant-future proof so :+1:.

[ 'tableCell', 'tableRow', 'mergeCell' ]

ps.: it's 'tableColumn' not 'tableCell' but I'm sure it's just typo :)

Yup, typo.

I'd also change these two commands:

"setColumnHeader"
"setRowHeader"

to setTable...

OK, and I see that no UI components other than the 3 main ones are registered in the component factory. So we don't need to be that cautious about names of these classes.

to setTable...

Hm... we'd also need to rename insertColumnAfter to insertTableColumnAfter, removeRow to removeTableRow. WDYT?
