This is a very trivial bug but it can cause discomfort working for the end user (he/she must save the file again and again).

Camel editor sometimes indicates that the file has been changed even if the file wasn't changed.

Steps to reproduce:
1. Open camel-context.xml
2. Move any pattern by drag and drop
3. The editor indicates that the file was changed but the file remains the same

Another situation:
1. Open camel-context.xml
2. Switch to another route
3. The editor again indicates the file was changed (actually, some tab spaces were added)
