FMSLogo Code

Thank Rosario Ruiz for providing a Spanish translation of the MSWLogo manual.
This served as a basis for the translating the FMSLogo manual into Spanish.

Add the Spanish documentation to the "website" target

Note that version 7.5.0 will include a Spanish manual, thanks to Rosario Ruiz whose translation of the MSWLogo it is based upon.

Remove the translation tables from the Spanish FMSLogo.
These are no longer needed, as the entire manual has been translated.

Integrate the spanish manual into the build.

Translate the glossary into Spanish

Clarify that MCI commands are always in English, even in the Spanish version of FMSLogo.

Translate the MCI examples for playing a video and playing an MIDI file into Spanish.

Fix a copy&pasted typo "la procedimiento" -> "el procedimiento"

Standardize on "asíncrono" for the translation of "asynchronous"
This seems to be what most computer-related texts use.
