Several enhancements

I recently switched from Eclipse to IntelliJ 13 and started using IntelliJCoder plugin when participating in TopCoder SRMs.  I have made several modifications and enhancements to it.  I hope you find these changes useful.

Features:
- Added hamcrest library to module if needed (JUnit 4.11 no longer includes hamcrest classes, and now requires the hamcrest library as a dependency)
- (Configurable: Module naming convention) Module names can be based on the class name (current behavior) (e.g. "Lottery" - one module per problem) or based on the contest name (e.g. "SRM 144 DIV 1" - one module per contest)
- (Configurable: Enforce time limit) Added execution time limit via @Test(timeout=####) to match the problem's limit
- Added memory limit via -Xmx vm parameters to match the problem's limit
- Added feature to save the problem's description to an html file
- Modified module creation to only create files if they don't already exist, includes module, class, test, and html.
- (Configurable:  Folder names) Made folder structure configurable: src, test, and resource folders can be changed
- Modified plugin settings screen to include new configurable options.  Split the configuration into 2 tabs. (see attached images - below)

The following shows an example of the file layout when using the two module naming styles.  Having the following information...

- contest: SRM 144 DIV 1
  - problem1: 
    - class: BinaryCode
    - method signature: String[] decode(String message)
  - problem2:
    - class: Lottery
    - method signature: String[] sortByOdds(String[] rules)
  - problem3:
    - class: PenLift
    - method signature: int numTimes(String[] segments, int n)


When *MODULE NAME MATCHES CLASS NAME*:
Produces the following layout...

- project: (uses current open project)
  - module1: BinaryCode 
    - src
      - BinaryCode.java 
    - test
      - BinaryCodeTest.java
    - resource
      - BinaryCode.html
  - module2: Lottery
    - src
      - Lottery.java
    - test
      - LotteryTest.java
    - resource
      - Lottery.html
  - module3: PenLift
    - src
      - PenLift.java
    - test
      - PenLiftTest.java
    - resource
      - PenLift.html


When *MODULE NAME MATCHES CONTEST NAME*:
Produces the following layout...

- project: (uses current open project)
  - module: SRM 144 DIV 1
    - src
      - BinaryCode.java
      - Lottery.java
      - PenLift.java
    - test
      - BinaryCodeTest.java
      - LotteryTest.java
      - PenLiftTest.java
    - resource
      - BinaryCode.html
      - Lottery.html
      - PenLift.html
