Cursor display issues when clicking document

[perrycate]

From Normal mode, when clicking on text anywhere in the document with the mouse, the cursor switches to it's Insert mode appearance (a single line) instead of it's Normal mode appearance (single character selected) despite Normal mode still being in effect.

Personally I would prefer that it switch to insert mode, or better yet allow the user to set this behavior in a config file somewhere, but regardless the cursor appearance should stay consistent.
