Add Localization

[stephenjang]

I did a completely rewrite for localization.
There are a lot of changes, but I only changed what is represented in the UI. Except for those related to data.

• Unlike L[] in AceLocale3, the _L[] metatable does not throw an error if there is a missing entry. _L[] is used as an optional entries in the package or list and the description of the list.
• Also, the description input of entry is changed to multiline 6 lines to check for long messages.
• Due to word order differences in languages like Korean, entries with multiple %s in the formatted strings have been changed to numbered variables (%1$s, %2$s...). Order-independent words like 'and' or 'or' are excluded.
• Modified built-in packs or lists to be displayed in Blizzard blue color.
• Added more power types (blood_runes, frost_runes, unholy_runes, happiness for WotLK).
• Moved the version check functions to namespace for use in locales. However, those functions have been reassigned in Hekili.lua for backwards compatibility.
• Modified SaveDebugSnapshot() function so that only the snapshots dropdown selector shows localization.
• Added a description to the tooltip in the MultilineEditor.lua file.
• Moved hideOmniCC to the Delays tab. I think that's probably a better place for it.
• Default values are shown as values for displayTemplate, if available, and the default value for frameStrata has been modified from "LOW" to "MEDIUM".
• Modified to get default values from displayTemplate if available. Also fixed the default value for frameStrata from "LOW" to "MEDIUM".
• Added GetPlainText() function for Import Log: Workaround for EditBox not supporting escape sequence for preposition or postposition.
• Added button disabled to avoid an error when the Import button is pressed on an empty profile and no profile exists.
• Show Heroism instead of Bloodlust if the player's faction is Alliance.
• The shadowmeld option is only available for Night Elf, otherwise it is disabled.
• Changed the package name of Demon Hunter from Havoc to Havoc DH. Because it's the same as Warlock.
• Removed word wrap escapes from messages and added the ns.WordWrapper() function.
• Added the ns.WARNING prefix to the namespace.
• I'm also working on a WotLK version. I'll PR it when it's ready.

Do you have any better ideas or thoughts?

Updated locales and fixed a bug that was causing a error in the actions list tab.
For now, I've removed the wrath messages. Unless you have plans to merge with the wrath branch in the future.

Hi @Hekili , do you have any further questions about this PR? I think I have time to submit a Chinese translation, but it might need to wait until @stephenjang 's work is merged into the main branch.

[Hekili]

If this is brought up to date, I will accept the PR. Thanks for the hard work.

I have been maintaining the Simplified Chinese version through global translation replacement for a long time, And shared in the largest Chinese wower forum. After the localization transformation is completed, I can immediately switch to the production of local language files. Looking forward to the 11.0 version being equipped with a complete localization.
