Add Makefile, man page, change config format, bump version v0.4.0

This commit pushes a lot of changes at once. Older config will no
longer work with this.

The file name will contain time in local timezone instead of UTC.

Makefile & man page was copied from tomasino's pb(1). (tomasino.org)

-  I use this to quickly backup some of my files. It works on profiles,
-  profiles are simple lists of files which get backed up.
-
-  *Note*: Backup file's mode will be changed to `0600'.

-2.1 Profile
+1.1 OpenBSD
 ───────────
 
-  Profile is a simple hash table (`%profile') which contains the list of
-  profiles. The profiles are mapped to a list of file paths which are to
-  be backed up.
-
-  You can run `help' to see all the profiles along with the paths.
-
-
-2.2 Options
-───────────
-
-  Some options can also be passed through environment variables. That
-  allows for configuration in shell rc file & the user can run leo
-  directly without looking at options.
-
-  ━━━━━━━━━━━━━━━━━━━━━━━━
-   encrypt  `LEO_ENCRYPT'
-   sign     `LEO_SIGN'
-   signify  `LEO_SIGNIFY'

-2.2.1 encrypt/sign
-╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌
-
-  `encrypt_sign' handles `gpg2' related functions. It passes `--yes' by
-  default.
-
-  • `encrypt' / `sign' can also be set in configuration file, one can
-    also configure it for specific profile.
-
-  *Note*: `gpg2' might compress the backups depending on your config.
-   Default is to enable compression, if you don't want this then add `-z
-   0' to `@options'. `-z' specifies the compression level & 0 means no
-   compression.
-
-
-2.2.2 signify
-╌╌╌╌╌╌╌╌╌╌╌╌╌
-
-  `signify' will invoke `signify(1)' & the file will be signed.
-
-
-2.2.3 gzip
-╌╌╌╌╌╌╌╌╌╌
-
-  `gzip' will compress the tar archive with `gzip(1)'.

   It's very easy to setup `leo', I made a demo video to show this. I
   already have Perl environment setup for this.

-═════════
-
-  This was Leo's initial description:
-
-        Leo is a program to run my personal scripts. You might not
-        find them useful, these were previously shell scripts that
-        I rewrote in Perl.
-
-  I had created a sync function initially & was going to expand it. Then
-  I decided to remove those sync functions because it was too complex, I
-  replaced then with simple `sh' scripts.
-
-  I added a simple `archive' function later & decided to turn Leo into
-  that function. So, it's not a meta-program anymore. I was thinking of
-  creating something that does all the things for me but that'll be too
-  complex.
-
-  Later on the same day I removed dispatch table & switched to using
-  simple hash of lists to store backup paths mapped to profiles. And
-  also changed the word "archive" to "backup" everywhere.
-
-  I added a simple INI based config file before 0.1.0 release.
