Allow passing arguments to compiled scripts

now the installer is not added as a `--compile` step but instead baked into the binary itself

 There's a script to call `./build.sh`, make a new release and publish it etc., it's `../release.sh`. You most likely can't run it yourself though.

-# Attaching the installer:
-# The installer is not shipped separately and instead bundled with the binary by doing this.
-# Bundling is the same thing as compiling a script as a user.
-# It is possible to repeatedly compile a binary, with each script being appended at the end each time.
-# Only the last one actually executed - and only if no params are passed to the program.
-# There's no point in compiling multiple times, but it allows us to ship a default script (the installer)
-# for when no arguments are passed.
-# In other words, this is possible for a user:
-#     ahk_x11 --compile script1.ahk && ./script1 --compile script2.ahk && ./script2
