Data Cleanup and K'kree/Hiver borders

A few more borders in Hiver and K'kree space:

• Added borders for Gn'hk'r (Gelath) and Gh!hken
• Added allegiances and generated borders for Leonidae and Extolian
• Reworked Hinterworlds borders to connect with Leonidae

...and then some data cleanup that I realized was necessary when I got there!

I noticed in some of the “outlying” sectors (i.e. non GEnie data) that the UWP parser was misinterpreting some worlds (e.g. thinking the PBG was a trade code, the allegiance was PBG, and the stellar data was the allegiance) or missing some worlds entirely. This is because when I started I used a very loose pattern matching system to try and incorporate lots of different data sets without editing the sector data itself. This turns out to be intractable, so I’ve given up and tweaked the data in some sectors to be a little less quirky, and tightened up the parser. The site should also be marginally faster in loading data (i.e. if no-one has viewed a region in a few seconds).

It's possible that a few worlds have now suddenly popped into existence elsewhere. If you notice borders that are shy a few parsecs of a world, let me know!

Data tweaks:

• Replaced blank allegiances with -- in Leonidae
• Fixed badly generated PBGs for Uu (Teahloarifu 0319) and Ukhihesi (Teahloarifu 1431)
• Added spaces to Extolian and Ktiin’gzat sector data for correct Zone and PBG parsing
• Fixed PBGs for Foreven (blank B to 0)

While I was there, I wrote some tools to validate the data and corrected some simple typos or missing digits in other sectors:

• Arkadish (Mendan 0515)
• Unnamed (Zhdant 1206)
• Khipge (Zarushagar 0914)
• Strand (Gushemege 0237) - missing digits in GEnie data; used Core data
• Ninkhur Sagga (Solomani Rim 2222) - replaced blank PBG with 100
