Paths in mike.default.ini

Also need to use the PathReplacements for all pathy things in mike.default.ini


merge-tool doesn't work anymore because of the "<left>" "<right>"? Split em up?

```ini
; Beyond compare
merge-tool=<A_PROGRAMFILES>\Beyond Compare /[0-9]+/\BCompare.exe "<left>" "<right>"
```

Read with:
```ahk
mergeTool := PathReplacements(ReadMikeIni("memory-diff", "merge-tool", true))
```
