Reload-ISE - Part III

I added some code to save using different encodings and to show the encoding of the current file.

I thought default for new files was utf8. Surprize it is BigEndianUnicode. But as long as it uses a BOM-Mark i will not complain. (Otherwise read my comments. ;-) )

Play and learn.

    .Synopsis
        Reload file asuming given encoding
    .Description
        Reload the file in the current editor asuming given encoding, 
        the file is not saved automatically. You can try other encondings on
        the unmodified file.
    .Example
        Reload-ISE utf8
        Reloads the file asuming utf8 encoding. This is useful when the file
        has no BOM
    .Example
        Reload-ISE
        Prompts for a codepage number and reloads the file using it
