Fix Composer version check

I've seen this for a few versions of VVV that in both Ubuntu 12.04 and 14.04 the below line of code would always evaluate to false, and as such, always install Composer instead of checking for an update:
```bash
if [[ -n "$(composer --version | grep -q 'Composer version')" ]]; then
```

I propose using the following, which seems to evaluate more consistently:
```bash
if [[ -n "$(composer --version --no-ansi | grep 'Composer version')" ]]; then
```

Bump VirtualBox VM memory allocation to 1024 from 512

1GB seems to be a nicer answer than 512MB by default. A Customfile
can be used to reduce or raise the memory footprint to another
level.

Instruct Curl to follow 302 redirect for Wordpress source files

Instruct Curl to follow 302 redirect for WordPress source files
Use HTTPS when downloading the latest WordPress package

See #350

"libcurl performs peer SSL certificate verification by default"
http://curl.haxx.se/docs/sslcerts.html

This is better practice and eliminates the current redirect from
HTTP to HTTPS. We'll leave the `-L` flag, as future redirects are
possible.

Thanks @nacin
