Installer needs to install curl at very beginning

[automationator]

The installer checks for internet access by using curl, which is not necessarily installed in a clean Ubuntu install.

ace@acedev:/opt/ace$ ./installer/source_install
sed: can't read /etc/apache2/envvars: No such file or directory
You are missing the SAQ_HOME environment variable.
Do you want to use /opt/ace as the value for SAQ_HOME?
1) Yes
2) No
#? 1
checking internet access...
unable to connect to google -- do you need to configure a proxy?
set your http_proxy, https_proxy and ftp_proxy environment variables and try again
you may also need to configure apt for a proxy
ace@acedev:/opt/ace$ vim installer/source_install 
ace@acedev:/opt/ace$ curl -m 5 'http://www.google.com'

Command 'curl' not found, but can be installed with:

sudo apt install curl
