Corrected 'configrue' typo across 19 install scripts

[pfeerick]

Corrects the configrue instead of configure typo that is present in most if not all the install scripts.

Basically a quick application of for i in *; do sed -i 's/configrue/configure/g' "$i"; done to apply the correction.

This is a more encompassing update than #4, but was brought to my attention by that update, so a big thank you @gulliverrr for raising the issue.
