Cannot save project with a hyphen in file name.

[Artur Bodera (Joust)]

For some reason names with hyphens are rejected.
I suspect that validator on file name field needs some relaxing.

Example file name: "new-project" or "new-project.xds" (save path is irrelevant)

Tested on Win 7, latest (auto-updated) version.

dash or hyphen can cause potential issues. Prefer the use of underscores instead of hypens

new_project or new_project.xds
