add coding/development files to Tools > Disk Analyzer

right now there is a large lump of "other files" listed when I run disk analyzer.

The files you detect are great, but I would like to see a category coding/development, which would tally files like

vb

php

js

css

html

htm

py

ps1

bat

c

cs

cpp

asm

sql

etc.

Just for reference, the lines-of-code counter "cloc"
