Merged legacy 2014 + 2024 content

[nikjft]

Thank you for pulling the 2024 content together! I put in a lot of hours today to bring the 2014 and 2024 together so you can take advantage of the much-vaunted backwards compatability features. These include the following collections and supporting compendiums:

• Sources/WizardsOfTheCoast2014: All the WotC materials with "[2014]" suffixed on the materials so it can be kept clearly separate from the 2024 rules
• Sources/Adventures2014: All the Adventures materials with "[2014]" suffixed on the materials so it can be kept clearly separate from the 2024 rules
• Sources/WizardsOfTheCoast2014Subclasses: All subclasses that are not in the 2024 PHB have been maintained without adjustment other than subclasses (schools, orders, etc.) aren't gained until level 3. PHB-contained subclasses have been removed.
• Sources/Adventures2014Subclasses: Same as above, for subclasses in the Adventures sources.
• Collections/WotC_2014_Legacy_Subclasses.xml: Just the subclasses from WOTC + Adventures
• Collections/WotC_2014_Legacy.xml: Just the 2014 WOTC and Adventures content with the suffixed [2014] on everything.
• Collections/WotC_Only_2024+2014.xml: Legacy + new content, with 2014 and 2024 content living happily side by side. Gives you the option to make any character you want from any edition and mix your 2014 and 2024.

I did not make any efforts to de-duplicate spells, feats, etc. between those books because I couldn't come up with an easy method to be able to delineate what's in both places and what isn't, unless I make a spell list of "Wizard [2014]" or something like that, which seems like a lot.

The WotC_2014_Legacy_Subclasses collection doesn't compile, instead creating an empty file. The base content would need to be added, so I removed that collection since that is what WotC_2014_Legacy.xml already does.
