Overwrites existing values of t_SI, t_EI

[jfgoodall]

vim-togglecursor overwites t_SI and t_EI preventing other settings from being applied (i.e. as shown in https://coderwall.com/p/if9mda/automatically-set-paste-mode-in-vim-when-pasting-in-insert-mode).

Patch to allow additional, external settings to be supplied as option variables:

Thank you for filing an issue. I'll have to think on this a bit more... all the terminal handling stuff can be rather tricky.
