v0.51.1

Improve error message importing native declaration - #871

Importing a native declaration as []int{}, Scriggo returns the error

importing package main, declaration "toc" is not valid

It is not clear why it is not valid. This change reports instead:

cannot import toc: to import a variable use a pointer to that variable

Update README file

Improve the example on templates, add a padded version of the logo and the badge for 'Go Report Card'

Add SECURITY.md file
