Title: Fix for #4602

* Adding a CanPass() proc to girder so projectiles can now sometimes pass through them, with varying percentage chance depending on girder subtypes ( 20%,25%,0% for girder, disloged, reinforced). Fixes #4602

* Fixing reinforced and disloged girders being called "reinforced" or "disloged" upon examination instead of "disloged girder" and "reinforced girder".

* Adding passtable and passgrille to mice for consistency, because chicks already have those flags.
