TINKERPOP-1653 Allow multiple scripts to be passed to gremlin.sh
https://issues.apache.org/jira/browse/TINKERPOP-1653
This is a non-breaking change and simply allows multiple `-i` and `-e`
options on gremlin.sh. The old method for passing a single script name to
gremlin.sh remains intact as well. Had to write a custom parser for the command
line arguments to do this because it doesn't appear that `CliBuilder` is
capable of parsing the in the manner necessary to support this feature
unfortunately.
Here's some example usage given these three scripts:
```text
$ more *.groovy
::::::::::::::
x.groovy
::::::::::::::
x = 1 + 1
::::::::::::::
y.groovy
::::::::::::::
y = args.collect{Integer.parseInt(it)}.sum()
::::::::::::::
z.groovy
::::::::::::::
z = "argument=" + args
```
This is old, now deprecated, method that is still supported:
```
$ bin/gremlin.sh x.groovy
\,,,/
(o o)
-----oOOo-(3)-oOOo-----
plugin activated: tinkerpop.server
plugin activated: tinkerpop.utilities
plugin activated: tinkerpop.tinkergraph
gremlin> x
==>2
```
Next with `-i` as usual:
```text
$ bin/gremlin.sh -i x.groovy
\,,,/
(o o)
-----oOOo-(3)-oOOo-----
plugin activated: tinkerpop.server
plugin activated: tinkerpop.utilities
plugin activated: tinkerpop.tinkergraph
gremlin> x
==>2
```
then with arguments:
```text
$ bin/gremlin.sh -i y.groovy 1 2 3
\,,,/
(o o)
-----oOOo-(3)-oOOo-----
plugin activated: tinkerpop.server
plugin activated: tinkerpop.utilities
plugin activated: tinkerpop.tinkergraph
gremlin> y
==>6
```
Next with multiple scripts:
```text
$ bin/gremlin.sh -i y.groovy 1 2 3 -i x.groovy
\,,,/
(o o)
-----oOOo-(3)-oOOo-----
plugin activated: tinkerpop.server
plugin activated: tinkerpop.utilities
plugin activated: tinkerpop.tinkergraph
gremlin> y
==>6
gremlin> x
==>2
```
Then with multiple scripts with other `gremlin.sh` options mixed in
```text
$ bin/gremlin.sh -i y.groovy 1 2 3 --color -i x.groovy -i "z.groovy x -i
--color -D"
\,,,/
(o o)
-----oOOo-(3)-oOOo-----
plugin activated: tinkerpop.server
plugin activated: tinkerpop.utilities
plugin activated: tinkerpop.tinkergraph
gremlin> x
==>2
gremlin> y
==>6
gremlin> z
==>argument=[x, -i, --color, -D]
```
Finally, note that you still can't mix/match `-i` and `-e` commands -
`CliBuilder` still rejects bad stuff like that:
```text
$ bin/gremlin.sh -i y.groovy 1 2 3 --color -i x.groovy -e "z.groovy x -i
--color -D"
-i and -e options are mutually exclusive - provide one or the other
```
