FZF_<shortcut>_OPTS affect FZF

- FZF_CTRL_T_OPTS, FZF_CTRL_R_OPTS, and FZF_ALT_C_OPTS work as specified in fzf documentation
- resolves kelleyma49#51

Verify arguments were passed in

- verify that parameters were actually passed in before attempting to use them
- FZF_DEFAULT_OPTS should work (resolves kelleyma49#48)

Install Pester 4

- hopefully fixes unit tests

Remove invalid Resolve-Path

Apply kelleyma49#45 to the base file

- PsFzf.psm1 is generated from other files

More attempts at improving load time

- BREAKING CHANGE: aliases are disabled by default;
call the function Enable-PsFzfAliases to enable previous behavior
- Aliases can be individually enabled through Set-PsFzfOption
- Aliases don't call Get-Command to speed up module load time
- BUG FIX: chord module parameters no longer overlap

Fix for markdown error

Remove build step to generate .psm1

Add shortcut for git branches

second step in rename workaround
