new major release

changes

• feature: support for relative paths within commands, e.g. if you typed b nano ..\file.txt (or used TAB to autocomplete the command) in Windows command line or PowerShell, the backward slashes \ will automatically be converted to forward slashes / to reference the same file under wsl
• moved aliases outside of the wsl directory (new location is %userprofiles%\wsl-alias), this is to avoid the following issue: microsoft/WSL#3487
• removed the privileged userl; wsl-alias now (optionally) adds the default wsl user permission to mount a drive without requiring a password, this also results in /mnt directory requiring 777 permissions (which is also set by the installer)
• rewritten parts of the code; much nicer with better understandable variable names
• changed the install path to ~/.wsl-alias

a note about wslpath: i was planning to implement it into this release to convert the current working directory from windows into the wsl path but came across this issue: microsoft/WSL#3246
since i'm using a veracrypt container most of the time, this solution wouldn't be suitable for me (and a lot of other people) so that's why i'll wait for wslpath to be fixed

Upgrading from v1

1. Backup your aliases from ~/.wsl/bin/win
2. Delete the old version: rm -r ~/.wsl and remove the old alias directory from the Windows environment var PATH
3. Install the new release, instructions in README
4. Recreate your old aliases (if you just move your old aliases into the new directory, they won't work)
