Implement "insert type definition of outer function under cursor".

[annaluiseblume]

This adds a function hdevtools#insert_type() which inserts the type definition of the outer function under the cursor. The definition is inserted right above the definition of the function.

The functions first gets the number of the first line of the outer function via the last line of output of hdevtools type <file> <line of cursor> <column of cursor>

This line number is then used to find the identifier of the function. The type is then determined via hdevtools info <file> <identifier>

@annaluiseblume I'm testing that branch and having issues. It uses build_command_bare, which ignores my hdevtools_options. If I change that call, I get an error that seems to pertain to an empty list, where l:type_lines[0] results in a `list index out of range:0. I'll leave it at that - sorry not to dig further, I don't know vimscript.
