Remove php extension on binaries

When scripts are installed into a directory in the system PATH, the script name should not include an extension such as .sh or .pl that denotes the scripting language currently used to implement it. The implementation language may change; if it does, leaving the name the same would be confusing and changing it would be disruptive.
