Latin American Spanish language overhaul

[protocultor]

For native speakers of the language, these changes provide a more professional-feeling translation, getting them to a quality closer to the original English language.

• More accurate translation (used the English original as a guide for this).
• Improved spelling and grammar.
• Better pagination, or separation of text between pages, without cutting sentences in half as in the current state of the translation. Altered linesPerBox when needed (not terribly different from AM_us).
• Removed usage of "Mexicanisms", going towards a more neutral language, more understandable to the rest of Latin America. (e.g. "resbaladilla" for the slide).
• Related to the last, removed "Spanishisms" that I assume came from the ES_es translation (e.g. "¡Tío! ¡Tío!").
• Added previously untranslated menu text.
• Full Dynos menus' translation.
• Full parity between "texts" and "texts-unconverted" versions of ES_la JSON files. "texts-unconverted" missed a lot of menu options from texts, mostly cheats.
