Tasks: TOP => haml:replace_erbs

The issue is that in line 46 of the erb2haml.rake file, it does this check:
if which html2haml.empty?

'which' is a linux (and I assume Mac) command. I replaced the 'which' with the windows semi-equivalent 'where' and it worked ok.

Thought you'd like to know that this is an issue.
