revise progress formatting to space-leading three digit percentages

[rivy]

Formatting was a bit off for progress when hitting 100%. I thought the leading zeros were also distracting. I can put those back in if you prefer them. It's just not what I'm used to seeing.

before

C:>rm -r build .xmake & xmake
checking for the architecture ... x64
checking for the Microsoft Visual Studio (x64) version ... 2015
building to: build\windows.release.cl.x64\bin\hello.exe
[00%]: compiling.release src\main.rc
[50%]: compiling.release src\main.c
[100%]: linking.release hello.exe

after

C:>rm -r build .xmake & xmake
checking for the architecture ... x64
checking for the Microsoft Visual Studio (x64) version ... 2015
building to: build\windows.release.cl.x64\bin\hello.exe
[  0%]: compiling.release src\main.rc
[ 50%]: compiling.release src\main.c
[100%]: linking.release hello.exe

There was no single location for the change, so I changed it throughout the code base. I thought about localizing it to a single code location, but I wasn't sure where it would be best placed. Future localization would probably be a good idea though in order to plan for alternative formatting (different color choices, etc).

Ok, thanks and I will move to a single code location in these days.

I have move it to the single location in dev branch. You can see #310 issue about theme.

set_text("build.progress_format", "[%3d%%]")
set_color("build.progress", "green")
