[IGBF-1337] Test the IGB release & Install4J update process - JIRA UNCC

Details

Document and test IGB release/update process for IGB installers.

IGB installer wrapper installed with any version of IGB should detect new versions of IGB and ask the user to update.

Testing process:

Deploy BioViz Web content on test site. See https://bitbucket.org/lorainelab/bioviz
Fork https://bitbucket.org/lorainelab/integrated-genome-browser, set up BitBucket pipelines to build installers
Create branch, edit codeBaseUrl setting in Install4J configuration file on branch (e.g., distribution/igb_7.install4j) to point to the test server
Run release pipeline on testing branch of IGB
Deploy artifacts on test site (see instructions in igb/release directory of BioViz test site)
Create dummy folders with mock next version of IGB (e.g., 9.0.2 if testing 9.0.1 installer). Edit updates.xml as required for the mock next version.
Download and run the installer you are testing. Run this version of IGB, then quit.
Log back into test site and update the symbolic link to point to the mock next version of IGB.
Run IGB.
Observe that the installer asks you if you would like to update IGB. Make sure the new version is installed and runs.
