Improvement: Respect .forceIgnore about force-source-clean

[ralphcallaway]

i.e. sample syntax is all "globby"

# Specify a relative path to a directory from the project root
helloWorld/main/default/classes

# Specify a wildcard directory - any directory named “classes” is excluded
**classes

# Specify file extensions
**.cls
**.pdf

# Specify a specific file
helloWorld/main/default/HelloWorld.cls

I haven't used .forceIngore to fully understand the sytnax... Here's the docs.

It's not immediately obvious to me if it's just using glob patterns or actually taking a more metadata context aware approach.

If it is just using globs, npm ignore makes it super easy to check

oh good question, i'd assumed it was globs, but can't say for sure. my reading of the docs doesn't seem to conflict with it being implemented with globs, i guess you could crack open the dependencies for the four commands that utilize .forceIgnore if this came up

but honestly this feels like a feature that wouldn't matter until there is fairly widespread usage, guessing there aren't a ton of people putting non-sfdx files in a sfdx folder

Made a pass... 9225647

Needs more testing

included in 0.0.4

Pretty limited testing

seems to be working well, had a clean failing due to merge conflict artifacts, added **.orig to .forceIgnore and was able to run without having to track down all the artifacts
