Consistently name saw tools and blades

[haveric]

Summary

None

Purpose of change

There were some inconsistencies in naming of these tools.

Describe the solution

Tools that are saws get split into two words. While I can find some references to bandsaw as being acceptable as well as band saw, I cannot for table saw and mitre saw. It seems logical then to have them all consistently in one style.

Sawblades of the saws get merged together. While I personally prefer this split as saw blade, both seem acceptable and the majority of references are already joined, so let's make the rest consistent.

Also fixed Boris's grammar

1. Leave inconsistencies
2. Consensus on alternative spelling being ok for one or all of the above and adjusting as necessary.
