Enhance tolerance towards versioning tools

[crazyfwed]

Here in my company we use SVN as versioning tool for CVI projects.

It is working fine enough. However, when users add files to the project, the .prj file is strongly modified.

Even if the lots of changes are quite useless, it may be more usefull if the changes would be minimal.

The worst case is when 2 users are comitting changes to the project file at the "same time", it finally ends with some conflicts.

So, please consider minimal changes to the project file for simple changes in the project (my secret wish is to, at least, keep the .prj file as text...)

I also posted this as a reply to another suggestion, but there should be a way to set the UIR editor to use .tui by default as those are more 'versioning tool' tolerant.
