expose select operator as normal command

[t9md]

Came up with idea while thinking for question in #890.

This PR expose Select operator as normal command.

• Select operator is super essential operator for vim.
• It's always complemented in visual-mode.
• Select operator is implicit operator used when text-object or motion is executed in visual-mode, in other word, it's used in operation which move cursor in visual-mode.
• When you do v j, j is executed in visual-mode.
• In this case, vmp treat j as Select operation with targeting j motion.

Why I haven't exposed this operator till now is, vmp's this part was not clean/consistent enough to expose user. Also I didn't understand for select operation clearly as I do now.

• This is general-purpose operator.
• So longer need to remember differnt g d(select-occurrence) keymap, :tada:
• If new keymapSToSelect conditional keymap have enabled, s is mapped to select operator, s o is equivalent to g d.(via conditional keymap)

  'atom-text-editor.vim-mode-plus:not(.insert-mode)':
  's': 'vim-mode-plus:select'

• Furthermore user can use s O to select subword-occurrence.
• s p to select paragraph, less keystroke than v i p.
• Since s enter operator-pending-mode, thus user can use p operator-pending-mode specific shorthand rather than normal i p.

Changes summary.

• Operator used in visual-mode is renamed from Select to SelectInVisualMode.
• Then now Select is normal operator which behave as in same way as other operator.
• Select operator just select target then finish(normal operator start mutation after select).
• The diff between Select and SelectInVisualMode is
  • SelectInVisualMode does not autoAccept preset-occurrence or persistent-selection so that user can modify selection without being interfered by pre-existing persistent-selection or preset-occurrence marker.

:+1: I think this is what I have been missing from occurrence, an easy way to visual select all occurrences rather than any other operation, I always got confused about and forgot about g (cmd)d (isn't command d the default?). Also while on the topic, is there a way to 'make cursors at occurrence'? I guess now it'd just be s o <text-object> <esc>?

What is your plan to replace s for its current behaviour of "change character"? Or don't you ever use that?

👍 I think this is what I have been missing from occurrence, an easy way to visual select all occurrences rather than any other operation, I always got confused about and forgot about g (cmd)d (isn't command d the default?).

I created set-cursor-at-start etc, operator in local experiment but removed. Here is it https://gist.github.com/t9md/c70f5d6528904601755422ae66124f26.

Why I removed is I thinks s o TARGET then escape is enough.

I WILL replace default s with select operator by keymapSToSelect conditional keymap. It's opt-in config disabled by default, so not breaking default s unless explicitly enabled it. But I will of course enabled this in my config.

@jackcasey we already discussed this question here: #890. Maybe that will be helpful :)

When you enable keymapSToSelect, what s can do is described in spec

vmp's spec is readable-dsl, you can think it as collection of example operation.
