Links not working with non-clean urls

Hello,

I ran into a few problems with the forward module while trying to implement it on my site and I thought I'd share how I fixed them.

1. One of my clients uses Windows-based hosting where clean urls are not available. It appears that the forward module assumes that clean urls are being used. My patch adds some code to check for clean urls and modifies the links appropriately.

2. I couldn't get the form-type "form" to display on any of my pages. I tracked the bug down to the fact that the variable_get('forward_display_'. $node->type, '0') variable wasn't being set in the variables table unless the content-type was actually updated from the admin/settings area. So, I modified the default value of the variable to "1" so that the form is displayed by default. I think a more correct way of fixing this would be to modify the install file, but I'm not 100% sure.

3. My installations are also using the SMTP module, and I found that the messages weren't being sent in HTML. I tracked the bug down to a lowercase "t" in "Content-type" - the SMTP module was looking for an uppercase "T". Anyway, my change capitalizes the "t" in the forward module (for the record, I also modified the SMTP module so that it wasn't case-dependent.

Hope this helps someone else.
