Simpler, more consistent file methods

[Capt0rr]

These look inconsistent to me:

File-ext? %data/file.txt        ; returns ".txt"
File-ext? %data/file.temp.png   ; returns ".png"

; Get filename with extension
Filename? %path/to/document.pdf ; returns "document.pdf"

; Get filename without extension (stem)
Stem? %path/to/document.pdf     ; returns "document"

; Get directory path
Dir? %path/to/document.pdf      ; returns "path/to"

I think they should be:

Ext?
Name?
Stem?
Dir?

...since they're relative to file-uri context we don't need the two "File" prefixes (one with "-", one without).
