Switch to approved verbs & add aliases

[God-damnit-all]

Originally I was proposing #9; then I remembered the unapproved verb warnings I've been suppressing from PowerShell 7.

The functions have been renamed using the approved verb Invoke, and with their previous function name added as an alias. Additionally, each function has a 2nd alias that is much shorter, for faster use.

Function	Renamed to...	2nd alias
Foreach-ObjectFast	Invoke-PSOneForeach	ForEachObj
Where-ObjectFast	Invoke-PSOneWhere	WhereObj
Group-ObjectFast	Invoke-PSOneGroup	GroupObj

Because I changed PSOneTools.psd1 to UTF-8 so that GitHub would stop interpreting it as a binary file (it was UTF-16 LE before) it caused a merge conflict with #7, so I went ahead and incorporated it. Just a minor release note fix.

Today I learned that aliases are allowed to have symbols in them. Maybe F% and F? for the fast foreach and fast where would be good additions?

Also, a brief tangent not necessarily related to this PR: you can even start aliases with two forward slashes, which would be an interesting way to add very short aliases in a cross-platform compatible way.
