TINKERPOP-1055 Gremlin Console FileNotFoundException can be misleading
https://issues.apache.org/jira/browse/TINKERPOP-1055
Some relatively minor refactoring required to get this working. Tested
manually only as I wasn't sure how to write tests around the console when it
was calling `System.exit(1)` on error. I first tested a "good" script:
```text
$ cat test.groovy
x=1
addItUp = {x,y -> x+y}
$ bin/gremlin.sh test.groovy
\,,,/
(o o)
-----oOOo-(3)-oOOo-----
plugin activated: tinkerpop.server
plugin activated: tinkerpop.utilities
plugin activated: tinkerpop.tinkergraph
==>1
==>groovysh_evaluate$_run_closure1@5536379e
gremlin> addItUp(1,10)
==>11
```
Then I tested a script that wasn't present on the file system:
```text
$ bin/gremlin.sh test1.groovy
\,,,/
(o o)
-----oOOo-(3)-oOOo-----
plugin activated: tinkerpop.server
plugin activated: tinkerpop.utilities
plugin activated: tinkerpop.tinkergraph
Gremlin initialization file not found at [test1.groovy].
```
Finally, I tested a script with an error in the script itself:
```text
$ cat test-fail.groovy
x = 1
y = x / 0
$ bin/gremlin.sh test-fail.groovy
\,,,/
(o o)
-----oOOo-(3)-oOOo-----
plugin activated: tinkerpop.server
plugin activated: tinkerpop.utilities
plugin activated: tinkerpop.tinkergraph
==>1
Bad line in Gremlin initialization file at [y = x / 0] - Division by zero
```

Better error reporting around gremlin.sh init script.
Refactored code a bit to catch exceptions related to IO on the init script
itself versus errors in line of code evaluation. Not sure how to write tests
here since we call System.exit(1) on error.
