New: enter insert mode after toggle_todo() and insert_link()

[renerocksai]

It is now possible to never leave insert mode when toggling todo or inserting a link!

I opted for jumping to the end of the line via simulated A key as the most sane option, especially for toggle_todo().

From the README:

• insert_link() : select a note by name, via Telescope, and place a [[link]] at the current cursor position
  • note:
    • this function accepts a parameter {i}. If true, it will enter input mode by pressing the 'A' key. This is useful when being used in a simple inoremap key mapping like shown in Bind it.
• toggle_todo() : turn a line into a - [ ] line, or toggle between - [ ], - [x], and - .
  • note:
    • this function accepts a parameter {i}. If true, it will enter input mode by pressing the 'A' key. This is useful when being used in a simple inoremap key mapping like shown in Bind it.
