LessCompiler runs for every build in watch mode

[g-cassie]

When running ember build --watch the LessCompiler task runs during every single build even when no changes have been made to any .less files. This significantly increases the total build time because the task takes 0.5-2.5 seconds and the rest of the build takes about 0.5-1.5 seconds.

I am not sure whether this is a problem with ember-cli, ember-cli-less or my config. Would appreciate some help on how I can debug this and figure out the issue.

Should not be an issue with this addon.
See #10

Sorry should have noticed that issue before I posted. I'll close this and comment over there if necessary.
