Update firstTimeInstall.sh source the cprt_bash_aliases from bashrc

[ErikCald]

Adds some code into the firstTimeInstall.sh to source our own bash aliases file. Has safety checks that will only put one copy of this code into the bashrc and will only try to source our bash alias file if it exists.

Also created a eaCPRT alias to edit the CPRT alias file.

Thank you for adding this.

Not sure if we will need it once we get the node management system running since the main aliases we used last year were build, and a handful of launch commands. We have the ./make.sh file for building too. Willing to hear other opinions.

Approving from a implementation standpoint. Up to @ChrisRusu1 as to whether this is a feature we want implemented.

We can add the specific aliases we used last time later on but I like the idea of having it in the repo so everyones got the same aliases
