Cache TW pages

[soul4soul]

When developing the converter I hit the wiki thousands of times a day. Each run of the program is over 2000 network requests. These requests are slow, waste bandwidth, and appear to cause throttling. One technique I use between runs is using a hard coded list of monsters to avoid all the network requests. A better solution would be to locally cache the wiki pages next to the executable to make them easy to manage and clear.

Expectations:

• Cache TW pages in plain text
• Store cache files local to executable in a folder
• Skip network request when file is found in local cache
• Optional: TTL for cache to go to network when files are over 24 hours old

The improvement is a nice to have, it mainly helps developers. For end users, that use TW as an input source there is no reason to run the tool more then once a day, even once a week is enough in most cases as the data on the wiki is updated slowly.
