As described in commit c5a2ea1dd8b8f85f7524bbdaa17844f2324d02c5 in the
kicad repository itself, the fp-info-cache file should not be checked
in to version control.

We shouldn't ignore -cache.lib files, because it causes missing components in your schema

http://kicad-pcb.org/help/file-formats/ specifically mentions this:

> `-cache.lib`: …​ a local copy of all the symbols used in the corresponding schematic, so that when the folder containing a KiCad project is copied to a different PC, the schematic can still be opened and printed and will still look the same as the original draughtsperson intended - even if that other PC does not have those symbols in its main libraries (or has symbols that coincidentally have the same name but are completely different).

- *.ses files are generated by Freerouting (which is the partially integrated autorouter)
- *.dsn files weren't actually being ignored

According to their website, the correct capitalization is KiCad, not KiCAD.

These are two other filetypes that KiCad creates before overwriting something.
