fixed bug in keyword parsing: seperator_after contained the whole string, causing it to be duplicated

Added first version of horizontal cycle to magic.mse-game/add_cards_scripts. Should be expanded upon when dialogs are done.
Altered magic.mse-game/packs to give illusion of handling mythic rares by including in rare pack items.
Tweaked text size on magic-new-token.

This allows auto replaces to be properly loaded from the game file.

Put ~ back in text_filter.  Why?  Because I believe that 99.9% of users won't realize to update their automatic text replacements, and will report an error that the tilde no longer functions.  Is it possible to just have automatic text replacements update when new ones are added, while keeping custom ones?

Commented out Invaders, Kree, and Skrull in VS symbol fonts because we likely won't have those images by 0.3.8 release.

@ is replaced with LEGENDNAME in automatic text replacements, as the community preferred @ as the shortcut.

Added new <nospellcheck> tag, to prevent spell-checking of words within.
Prevented spellchecking of anything a) matching a keyword or b) formed from a cardname atom
Replaced ` as LEGENDNAME alternative; I think it's a bug that it's gone

Fixed scroll issues; text no longer overlaps on package lists (still truncated, but this at least is better)

First Conflux keyword for Magic.
Improved Mythic Rare coloration.
Slightly improved creature type lists.

Bumping VS version.

Back to text rendered XYZ in Magic Mana fonts.  Left rendered symbols for XYZ in case things don't work out.

in documentation: @<tag>@ now highlights as a tag

simplified handling of punctuation is spellchecker, now checks for stand alone punctuation and double spaces.

always update the scrollbar when update()ing a GalleryList, otherwise the scrollbar is not set correctly on the new set window.

The magic game uses these features.

punctuation breaking is now handled by check_spelling function. Symbols are now handled correctly (i.e. they are considered to be always correct)

renamed SpellChecker::destroy to destroyAll, because the former conflicted with IntrusivePtrBase::destroy. The result was that destroy was called recursively and objects were freed multiple times.

This time adding the source files :)

The checker is used (experimentally) by the magic game file.

Currently the checker is only exposed through the script function check_spelling_word, which returns true if the word is spelled correctly.
