Support for Eclipse resource filters

[frozenspider]

It would be very nice to have at least some support for Eclipse resource filters feature. My use case - exclude target, project/project and project/target from Eclipse project view, right now resource filters are wiped out when project definition is re-generated. That being said, surely this isn't the only use case for resource filters.

@frozenspider You can do this already. Here is an example of how I exclude/include some files/folders in Eclipse.

These resource filters will... ...exclude following files and folders:

.git
.project
.classpath
.settings
node_modules
project/project
project/target

...include only following files and folders inside the target folder:

target/scala-[0-9].[0-9][0-9]/classes_managed
target/scala-[0-9].[0-9][0-9]/classes_managed/.*
target/scala-[0-9].[0-9][0-9]/test-classes_managed
target/scala-[0-9].[0-9][0-9]/test-classes_managed/

Just put it in build.sbt (actually I created a eclipse.sbt to remove noise from build.sbt):

// Add eclipse resource filters to the .project file
EclipseKeys.projectTransformerFactories ++= Seq(transformNode("projectDescription", DefaultTransforms.Append(<filteredResources>

I'll use this workaround for now, thanks! Still, I think the proper implementation of resource filters will be an asset and this issue stands.
