Enable full path specifications for NERDTreeIgnore

[PhilRunninger]

Description of Changes

Closes #1203

Added a new tag [[path]], for NERDTreeIgnore, that performs a pattern match on the full path of the node instead of just the last component of it. This is useful if you have a particular folder that you want to be hidden, while still showing every other instance of that folder. For example,

let NERDTreeIgnore = ['tmp/cache$[[path]]']`

will cause NERDTree to ignore /tmp/cache and /home/foo/projects/bar/tmp/cache, but /spooler/cache and /usr/bin/cache will be displayed.

The path regex needs to be compatible with the OS you're using, so for Windows, you would need to escape the backslashes, like so: 'tmp\\cache[[path]]' or 'C:\\Users\\foo\\tmp\\cache$[[path]]'.
